15 Best Price Comparison Websites & Apps to Save Money

The best price comparison tools for US and Canadian shoppers are Google Shopping for checking prices across thousands of stores, CamelCamelCamel and Keepa for Amazon price history, ShopSavvy for scanning barcodes in a store, and Slickdeals for deals other shoppers have already vetted. Below are 15 sites and apps with what each one does well and where it falls short, plus four extra tools for coupons, weekly flyers, and Canadian deals.

1. Google Shopping

Website: Google Shopping

Google Shopping (the Shopping tab in Google Search) pulls listings from thousands of online and local stores into one page. Open a product and Google tells you whether the current price is high, low, or typical compared with the past three months, and shows price history by retailer. Tap "track price" and Google emails you when the price drops at any store (Google). It is the quickest first check before buying almost anything.

2. PriceGrabber

Website: PriceGrabber

PriceGrabber is one of the oldest US comparison shopping sites. Connexity, the company behind Bizrate, bought it in 2015 (Retail Dive). It lists products by category with offers from several retailers, so it works as a second opinion after Google Shopping, but it has none of the price history or alert tools that the newer apps on this list offer.

3. ShopSavvy

Website: ShopSavvy

ShopSavvy lets you scan a barcode or search for a product and see prices from tens of thousands of stores, sorted lowest first. It also shows price history and sends price-drop, deal, and back-in-stock alerts. It runs on iPhone, iPad, and Android, with browser extensions for Chrome, Edge, and Safari (ShopSavvy). Scan an item in the aisle before it goes in the cart to see whether it is cheaper online or at another store nearby.

4. CamelCamelCamel

Website: CamelCamelCamel

CamelCamelCamel tracks prices on Amazon, including Amazon.ca, and shows a price history chart for each product, so you can tell whether a "deal" is the lowest price in months or just a return to normal. Set a target price and it emails you when the item drops to it. The free Camelizer browser extension adds the chart to Amazon product pages, registration is optional, and it never asks for your Amazon login (CamelCamelCamel).

5. Honey

Website: Honey

Honey, owned by PayPal, is a free browser extension that tests coupon codes at checkout. Its Droplist tracks prices on items you save from participating stores and notifies you when one drops (Honey). Honey fell from about 20 million Chrome users in 2024 to 14 million by July 2025 after a video showed it taking affiliate credit for purchases, and Google tightened its Chrome rules for affiliate extensions in response (9to5Google). It still finds codes and price drops, but check the codes on a store's DealHack coupon page as well.

6. PriceRunner

Website: PriceRunner

PriceRunner is a big European comparison site with its own websites for the UK, Sweden, and Denmark. Klarna bought it in 2022 and uses its engine for the price comparison tool inside the Klarna app, which launched in the US that year (PaymentsJournal). US shoppers get the most from it through the Klarna app; the UK site is only worth checking if you buy from British stores.

7. BizRate

Website: BizRate

Bizrate is Connexity's original comparison site (the company was called Shopzilla before 2014) and still lists products by category with offers from several retailers. Like PriceGrabber, it is best used as a second check on a price you found elsewhere.

8. Slickdeals

Website: Slickdeals

Slickdeals is a US deal community where members post deals and vote on them, so the best ones reach the front page within hours. In the app you can set deal alerts for a product, store, or category, such as "laptop" or "shoes," and choose how often you hear about matches (App Store). Read the comments before you buy: members often point out a lower price elsewhere or a better model for the same money.

9. Price.com

Website: Price.com

Price.com combines price comparison with cash back and coupons. It has a Chrome extension and separate versions for the US, Canada, and other countries (Price.com), which makes it one of the few tools here that pays you back on top of finding a lower price.

10. BuyVia

Website: BuyVia

BuyVia is a free app with a barcode and QR scanner, product search, daily deals, and promo codes (App Store). It has been around since 2012, but recent app reviews are mixed, so treat it as a backup to ShopSavvy rather than your main scanner.

11. Shopping.com

Website: Shopping.com

Shopping.com is one of the original comparison shopping sites and still runs top products and top deals pages. Its listings are thinner than Google Shopping's, so use it as a quick cross-check rather than your only search.

12. Idealo

Website: Idealo

Idealo is a German price comparison company whose product comparison covers European countries only. Its English-language site is a flight search that compares fares from many airlines, including routes to and from the US and Canada (idealo). Use it when you are pricing a trip, not when you are buying products at home.

13. Trivago

Website: Trivago

Trivago compares hotel prices from booking sites such as Expedia, Booking.com, and Hotels.com and shows the cheapest rate it finds for each property. Trivago does not sell rooms: you click through and book with the site that offers the price, so check that site's cancellation terms and taxes before you pay.

14. Keepa

Website: Keepa

Keepa does what CamelCamelCamel does with more detail. Its free browser extension puts a price history chart directly on Amazon product pages for Amazon.com, Amazon.ca, and other Amazon stores, and you can set a watch that alerts you when a product drops below your target price or comes back in stock (Firefox Add-ons). Hover over a product link to preview its price history without opening the page.

15. Shopmania

Website: Shopmania

ShopMania compares prices from US online stores on shopmania.com and runs separate sites in 16 European countries. Product pages add price history, specs, and user reviews, and you can save items to a favorites list (ShopMania).

Other tools worth adding

• Capital One Shopping: a free extension and app that applies coupon codes at checkout, tells you when prices drop on products you viewed or bought, and gives rewards at stores such as Walmart. You do not need a Capital One card to sign up.
• PriceBlink: a browser add-on that stays hidden until it finds a lower price or a coupon for the product you are viewing.
• Flipp: weekly flyers from US and Canadian stores in one app, with digital coupons you can load to store loyalty cards and a shopping list that matches items to current deals.
• RedFlagDeals: a long-running Canadian deal forum whose free app adds flyers and deal notifications.

How to save more with price comparison tools

A comparison site tells you who is cheapest today. These habits turn that into real savings:

1. Set alerts weeks ahead: add items to Google Shopping, CamelCamelCamel, or Keepa a few weeks before Black Friday or Prime Day so you know the normal price and can tell whether a sale price is real.
2. Trust the chart, not the "was" price: a crossed-out list price is set by the seller. A three-month price history shows what the item has sold for.
3. Track similar models too: last year's laptop or TV often drops further than the current model, so watch both.
4. Stack savings at checkout: once you know the lowest price, look for a coupon code and a cash back offer at the same store, and check whether the store will accept a competitor's coupon.

How to Choose the Right Price Comparison Tool for Your Needs

Most shoppers need two or three of these tools, not all 15. Pick by how and where you shop.

1. For General Online Shopping

Start with Google Shopping, which covers the most stores and tells you whether a price is high or low for that product. Use PriceGrabber, Bizrate, or Shopping.com as a second check.

2. For Tech and Electronics

In a store, scan the box with ShopSavvy. Online, check the Keepa or CamelCamelCamel chart for anything sold on Amazon, and set a Slickdeals alert for the model you want.

3. For Canadian Shoppers

Google Shopping, CamelCamelCamel (Amazon.ca), Keepa, and Price.com all work for Canadian shoppers. Add RedFlagDeals for Canadian deal threads and Flipp for weekly flyers from Canadian stores.

4. For Amazon Enthusiasts

Install Keepa or the Camelizer extension and look at the chart on every Amazon product page before you buy. Set a target price on anything you can wait for.

5. For Cash Back and Coupons

Honey and Capital One Shopping test coupon codes at checkout, and Price.com and Capital One Shopping add cash back or rewards on top. Compare what they find with the codes on DealHack's coupon pages for stores such as Walmart, Target, and Best Buy.

Conclusion

No single site covers every store. For most purchases, check Google Shopping first, look at the Keepa or CamelCamelCamel chart for anything on Amazon, scan with ShopSavvy in a store, and set alerts on big-ticket items weeks before the sales you plan to shop. Then look for a coupon before you check out.
