Keepa

This allows you to see the best time to purchase a product based on your needs. This chart has saved me from purchasing products for tens of percentages above their frequent lowest prices, and that feels good.

Price notifications are a way to keep you informed about the latest prices for goods and services.

CamelCamelCamel

Keepa’s is a browser extension that allows users to keep track of their online activities and share them with others. CamelCamelCamel offers the same feature, but in addition, it also allows users to add extensions to their browsers.

Keepa offers a great website, but it can be a little too polished for some users. CamelCamelCamel offers more features for those who want them, and its charts are better than Keepa’s.

SlickDeals

SlickDeals has been curating and selling cameras for years, and they’ve learned a lot about how to do it. They caught the $13,000 camera being sold on Prime Day 2019, for example, and they’re always on the lookout for new opportunities to make money.

SlickDeals is a coupon tracker that also has an official browser extension. This extension is more like Honey than Keepa or CamelCamelCamel, and it can be used to track coupons and prices. The advantage over the other two trackers on this list is that SlickDeals has an app for both iOS and Android.
