How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- ShopSavvy is the purest price comparison app, with barcode scanning and prices sorted lowest first across many stores.
- Honey and Capital One Shopping add automatic coupons at checkout, while Rakuten and Price.com focus on cash back.
- Slickdeals is best for finding deals other shoppers have already vetted, rather than for comparing one exact product.
- The lowest listed price is not always the best deal once shipping, taxes, coupons, and cash back are counted.
- Use one comparison app and one cash back app together, and check the final checkout total before you buy.

The best price comparison apps

ShopSavvy has compared prices since 2008, and it remains the most direct tool for the question behind this search, which is where a product costs least. Scan a barcode in a store, or search by name, and ShopSavvy shows prices across tens of thousands of stores, sorted lowest first. The site states that no store can pay to rank higher, which matters because a comparison that sells top spots is an ad, not a comparison. Price drop alerts let you set a target price and get notified when a check finds a lower price, and back in stock alerts cover sold out items.
ShopSavvy also offers a browser extension and a desktop app, so you can compare prices while shopping online as well as in a store. The free apps include ads, and ShopSavvy Pro removes them, though the core comparison stays free. Coverage is strongest for electronics, home goods, and common retail products, and thinner for niche or handmade items. ShopSavvy fits shoppers who want a clean lowest price answer before buying. It fits less well for shoppers who mainly want coupons or cash back, since those features sit in other apps in this list.
What we like- Scan a barcode or search to see prices lowest first
- Price drop and back in stock alerts
- No paid ranking for stores
Watch out for- App is free with ads, and removing ads needs Pro
- Coverage varies by product category

Honey, now part of PayPal, is best known for finding coupon codes without manual searching. Add the browser extension, shop as normal, and at checkout Honey tests available codes with one click and keeps the code that saves the most. Droplist lets you save an item you are not ready to buy and get notified if Honey detects a price drop at that store. On Amazon, Honey compares sellers and factors in shipping and Prime status, which helps because the lowest Amazon listing is not always the cheapest delivered price.
Honey is a checkout tool first and a comparison tool second. It does not scan barcodes in a physical store, and its price history is tied to stores it supports, which number more than 30,000 according to its site. Coupon codes also fail often, especially for stores that restrict codes to new customers or to specific items. Honey fits online shoppers who already buy through a browser and want codes tested for them. Pair it with ShopSavvy for a fuller picture, since Honey finds codes while ShopSavvy finds the lowest base price.
What we like- Tests coupon codes automatically at checkout
- Droplist price tracking
- Amazon price comparison including shipping and Prime status
Watch out for- Coupon success varies by store
- Price comparison is narrower than ShopSavvy for in store scanning

Capital One Shopping, formerly Wikibuy, combines coupons, price tracking, and rewards in a browser extension and app. It searches for coupon codes at checkout, shows rewards rates for stores, and highlights price drops on products you follow. You do not need a Capital One credit card to use it, which surprises some shoppers who assume it is only for cardholders. Rewards can be redeemed for gift cards and other options depending on the current program, and the homepage shows active offers with stated spend thresholds and caps.
Rewards are the weak point for planning. Rates, caps, and eligible stores change frequently, and some offers need activation on the homepage before you shop, so a reward you expected may not track if you skipped that step. Capital One Shopping fits shoppers who want coupons and rewards in one extension and who check offers before buying. It fits less well for in store barcode scanning, where ShopSavvy is stronger, and for shoppers who want a simple cash back payout rather than a rewards catalog.
What we like- Automatic coupons and rewards at many stores
- Price drop alerts
- Works without a Capital One card
Watch out for- Rewards rates and offers change often
- Some rewards need activation before purchase

Rakuten is the largest pure cash back tool in this list, with more than 3,500 brands and more than 17 million members stated on its site. Join for free, start a shopping trip through Rakuten or with the extension active, and earn a percentage back on eligible purchases. Cash back stacks on top of store sales and, in many cases, on top of coupons, which is why Rakuten users often pair it with a coupon extension. Payouts go by PayPal, check, or gift cards, with American Express members able to choose Membership Rewards points instead of cash in some cases.
The main limit is timing. Rewards are usually sent every three months, not after each purchase, and cash back is confirmed only after the store's return window closes. Rates also vary by store and by product category, and a high headline rate may exclude sale items or specific brands. Rakuten fits regular online shoppers who buy from major retailers and who are happy to wait for a quarterly payout. It fits less well for shoppers who want an instant discount at checkout, since cash back arrives later.
What we like- Cash back at more than 3,500 brands
- Extension applies coupons at checkout
- Payout by PayPal, check, or gift cards
Watch out for- Cash back is paid quarterly in most cases
- Rates vary by store and category

Slickdeals works differently from the other tools here. Instead of comparing one product across stores on demand, it shows deals found and voted on by a large community, with front page deals, coupons, and deal alerts for products you follow. A deal with many votes and comments is more likely to be a real saving than a random listing, and comments often note price mistakes, shipping costs, or a better alternative. That community check is valuable for electronics, tools, and seasonal sales, where a headline price can hide a catch.
Slickdeals is not a substitute for a direct comparison. It will not scan a barcode in a store, and it will not tell you the lowest price for a specific item that no one has posted as a deal. Popular deals also sell out quickly, so an alert needs fast action. Slickdeals fits deal hunters who enjoy browsing, setting alerts, and checking comments before buying. It fits less well for a shopper who wants a single lowest price answer for one product right now, which is ShopSavvy's job.
What we like- Large community that votes on deals
- Deal alerts for specific products
- Coupons and promo codes alongside deals
Watch out for- Deal quality varies and popular deals sell out fast
- Not a barcode scanner for one product

Price.com tries to combine the best parts of this list into one platform. Search once and it pulls offers from participating stores, including new, used, refurbished, and rental options, and ranks them by what you actually pay after coupons and cash back. The browser extension tests coupons at checkout, and cash back lands in a wallet that can be withdrawn to a bank, PayPal, Venmo, or Zelle, or turned into gift cards, crypto, or donations once a $5 balance is reached. Price drop alerts watch a product and notify you when it falls.
The trade off is youth and tracking rules. Price.com is newer than ShopSavvy, Honey, or Rakuten, so it has less community history to judge long term reliability. Cash back also only tracks if you start at Price.com or have the extension active, and using an outside coupon can overwrite tracking and cancel cash back. Price.com fits shoppers who want one tool for comparison, coupons, and cash back, and who will follow the tracking rules. Shoppers who prefer a long established cash back brand may still use Rakuten alongside it.
What we like- Compares new, used, refurbished, and rental prices together
- Automatic coupons
- Cash back wallet with many payout options
Watch out for- Newer brand with less community history than Slickdeals
- Cash back needs tracking through its link or extension

CamelCamelCamel is the specialist in this list. It tracks Amazon prices only, and it does that job with more depth than any general comparison app here. Paste an Amazon product link into its search box, or create a price watch, and you see a price history chart for that product plus an option to get an email alert when the price falls to a level you set. The homepage states it is a free Amazon price tracker, and it also lists highlighted deals and top price drops it has found, which helps if you are browsing rather than tracking one item.
The limit is scope. CamelCamelCamel will not compare Amazon against Walmart, Target, or another retailer, and it will not scan a barcode in a store. A price history chart also shows what a product cost in the past, not what it will cost next week, so a chart that shows a lower past price is a reason to wait or to set an alert, not a promise of a future drop. CamelCamelCamel fits shoppers who buy a lot on Amazon and want to know whether today's price is high, low, or average for that item. Pair it with ShopSavvy when you want to check whether another store beats Amazon's price.
What we like- Free Amazon price tracking
- Price history charts for millions of products
- Email alerts when a watched price drops
Watch out for- Tracks Amazon only, not other retailers
- No barcode scanning for in store shopping
How we chose
We compared vendor homepages, pricing pages, app listings, and public reviews, and we weighed store coverage, barcode scanning, price history, coupon success, cash back rates and payout timing, and ease of use. We did not claim hands on testing, and we listed only tools with a working official homepage during this review. Where a rate, fee, or payout rule was not confirmed for the reader's purchase, we wrote See website or described the rule in general terms rather than quoting a changing offer.
Getting the true lowest price
Start with the product, not the store. Search ShopSavvy or Price.com for the exact model number, including size, color, and configuration, because a cheaper listing for a different variant is not a saving. Check shipping, taxes, and return costs next, since a store with a lower product price and high shipping can cost more delivered than a slightly higher priced store with free shipping.
Coupons, cash back, and timing
Apply coupons before cash back in your thinking, because some stores cancel cash back when an outside coupon is used. Start the purchase through the cash back tool or with its extension active, then let Honey or Capital One Shopping test codes, and check the final total before paying. For a non urgent purchase, set a price drop alert and wait two to four weeks, since electronics and home goods often fall after a launch or before a holiday sale. For an urgent purchase, buy at the best delivered total you can find today rather than waiting for a deal that may not come.
Frequently asked questions
What is the best price comparison app for in store shopping?
ShopSavvy is the best choice for in store shopping, because it scans barcodes and shows prices across many stores sorted lowest first. Honey, Capital One Shopping, and Rakuten are stronger for online checkout, coupons, and cash back than for in store scanning.
Do price comparison apps really save money?
They save money when you compare the exact product, including shipping and taxes, and when you use coupons and cash back correctly. They save less when you compare a different variant, ignore shipping, or buy a deal you did not need because it looked cheap.
Is Honey free to use?
Yes, Honey is free to install and use, and it earns money through affiliate commissions from stores. Coupon success varies by store, so Honey may find no working code for some purchases, and that does not mean you overpaid if you already checked the base price elsewhere.
How does Rakuten cash back work?
You start shopping through Rakuten or with its extension active, buy from an eligible store, and earn a percentage back once the store confirms the purchase after its return window. Payouts are usually sent quarterly by PayPal, check, or gift cards, depending on your choice.
Can I use more than one price comparison app at once?
Yes, and many shoppers do. Use ShopSavvy or Price.com for the lowest price, Honey or Capital One Shopping for coupons, and Rakuten or Price.com for cash back, but check that an outside coupon does not cancel cash back tracking on that order.
Why does the same product cost different prices at different stores?
Stores set prices based on stock, shipping costs, supplier terms, and promotions, and prices change daily. A price comparison app shows a snapshot at the time of the check, so recheck the final checkout total before you pay, especially for electronics and seasonal items.
