A good app with tons of cool features. As far as I can see it works fine, the most useful feature probably being the price graph under every product.

However Keepa is sometimes extremely slow when it comes to notifying you of a price change. Like hours too slow.

First of all it seems to only be able to refresh your tracked product once an hour.
And then when it does refresh, it can delay sending you the notification even further for some reason.

I tried using it to track an extremely in-demand product, which flew off the shelf almost immediately after it got there. Keepa sent me a heads up on messenger. 2 hours after the thing sold out.

This method of operation/occasional hiccups are probably fine when trying for regular amazon deals that normally last a few hours(which is what I will continue to use it for), but for tracking availability, it's not optimal.

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.
