Keepa is my favorite tool for shopping on Amazon. It’s a fantastic app that empowers users and helps them make better purchasing decisions. I’ve been using it for about 2 years. I use it primarily for checking prices when I shop, although it has nice features for price notifications/alerts as well. When I shop, I’ll look at the Keepa chart (it’s right on the Amazon page a bit below the product listing) and see if the item is currently priced low or high relative to its price history. Usually I have the price history set to look at 3 months, but I regularly toggle it to a year or the entire history of the item to look for trends. If an item has a history of going on sale at certain times of the year, I will plan to buy it then. I LOVE this app for that. I recommend it to everyone who shops on Amazon.

good

When I use it, I get an error message：One time anti-bot check

I tried uninstalling and restarting Firefox, but it didn't recover.

Very useful addon and very lovely embedded in the Amazon pages. Like it just belongs there. 👍 Thank you very much for the work. Not just the addon, but the webpage too. 🤩
Is there actually a way (app?) to get a flash deal reminder/popup on mobile devices? I get a mail but then forget about it 😟

Do you use Amazon? Then you must use Keepa. Not should. *Must.*

The amount of money I've saved from using Keepa has to be in the thousands now. Given the insane value it provides (not to mention the breadth of analysis and collation it performs in order to provide that value), it's borderline incomprehensible to me that it's a free-to-use service.

The only other browser extensions I've gotten comparable value from, and am equally thankful for, are ad suppression-related. If you use Amazon even infrequently, Keepa is a top 3 MVP browser addon, with a bullet. If you use it often, as I do, it's indispensable; by virtue of the amount of money I've saved using it alone, it's far and away the best.

I'll *definitely* be buying the Pro version and donating to the devs. Immensely grateful for this gem of a plugin.
