Adding my two cents here, honestly the email alerts are usually a total bust. When I was hunting for a specific shade last year, I wasted so much time waiting for those emails that never came on time. I eventually just set up a dedicated browser extension that monitors changes on the product page itself. Be careful though, some of those tracking tools are super buggy or might steal your data if you arent careful with which ones you install. I just stuck to a basic one that refreshes the page every few minutes. Just make sure to clear your cache every now and then so you arent looking at an old version of the site. It takes a bit of technical setup but it saved me from paying those insane reseller markups.

> Do i just need to sign up for emails or is there some other app everyone uses for this? Honestly, the email alerts are super slow. In my experience, by the time the notification hits my inbox, the stock is already gone. I found PriceDropCatch a while ago and it is way better than manually checking. It polls inventory data much faster. That is the only way I snagged my current setup.

To add to the point above: just check Sephora in the mornings. Seriously, their stock updates way faster than the official site. Maybe look for similar blushes from brands like Tower 28.
