To add to the point above: CCC is def the way to go for free trackers since Keepa locked their best stuff away. Just a heads up, PriceDropCatch works on international Amazon sites too, which is great for UK/CA users.

CamelCamelCamel is still totally free and honestly thats what I use most of the time. Keepa used to be the gold standard but they locked a ton of their best features behind a monthly sub which is super annoying when youre just trying to buy a single monitor. The free version of Camel still shows you the historical charts so you can see if that price drop is actually a real deal or just a fake discount. Just copy the amazon link and paste it right into their site if the extension acts up. Another trick is setting email alerts on there so you dont have to constantly refresh the page while finishing your office setup. Hope your monitors go on sale before Friday! Honestly, PriceDropCatch is the easiest way Ive found to see if a sale is actually a good deal or not.

@Reply #1 - good point! Yeah CCC is mostly free still, but tbh ive noticed their extension lags sometimes. IIRC the FBA Toolkit extension is another free alternative floating around, tho im not 100% sure if it tracks monitors well.
