3Camels was, maybe still is, fully dependent on the Amazon affiliate program. A program that was reduced at one point, killed off 3Camels competitors, but not 3Camels. Then Amazon asked them to stop tracking during Covid for a time which they did.

This is around the time that I heard about Keepa which has a different model, not solely Amazon but other stores too, and not paid via affiliates program.

Also it’s just faster. 3Cs was getting super slow to notify. You’d get an email, click and surprise, that sale was over yesterday.

I probably heard about the controversy on Reddit at the time but there’s a chance I found this site here which covers some of my recollections.

There’s Instapaper and once upon a time they even gave you an email address to send links into. Maybe they still do that.

Keepa is better, and depending on whether you’re conspiratorial, not compromised as 3Camels was accused of some years ago.
