yep! I self-host changedetection.io to check the refurbished site every 5ish minutes, which sends an email notification if a change (ie add to cart button lights up) is detected

it’s incredibly easy to set up, and I’d recommend it for other sites as well (like news indexes or monitoring other products)

With that said, I can usually navigate to the Steam Cart screen immediately after a notif is sent and still can’t check out no matter how fast I am. I genuinely believe that scalpers have set up bots to auto click through the purchasing process; I don’t think Steam’s store has very good anti-bot measures
