Ive been an Amazon power user for years so I usually know all the shortcuts but I am seriously stuck right now. I have three different carts open across different browser profiles—mostly office supplies and bulk snacks for a local youth center project I'm finishing by Friday. I really need to merge these into one checkout to stay under my $500 budget and track the taxes right but copying every single ASIN manually is a nightmare.

I tried one extension but it just crashed my chrome session and didnt save anything. Is there a legit browser extension that actually works for merging separate Amazon carts quickly? I gotta get this order placed in the next hour or the shipping window closes...
