Honestly, you're not dreaming but you should definitely be careful with Share-A-Cart. I've used it for huge Adirondacks hauls and it basically works by generating a code that others use to pull items into a shared space. Just make sure everyone is using the same Amazon domain or it glitches hard. I would suggest having one person double-check the final list before hitting buy so you dont buy duplicate tents.

To add to the point above: managing a shared list for something big like the Adirondacks is a total vibe but also a logistical nightmare if the tech fails. I've been there with the whole 50-link copy-paste mess and its honestly the worst. If youre finding other extensions a bit glitchy with big carts, you might want to look into alternatives that focus more on the link-sharing side rather than a live cloud sync which usually breaks anyway when too many people are clicking around. I usually just use Cart To Link to send my whole list to my roommate or group chats whenever we're prepping for a festival or camping. It basically bundles your entire Amazon cart into one single URL that anyone can open. They click it, and boom, all the items move into their own cart instantly. Its way more stable than trying to have five people logged into the same session at once. Plus, it handles the tax and shipping math better once everyone sees the final checkout screen on their own end. No weird crashes so far and it works with basically any browser. Its been super reliable for me even with like 30+ items in the basket. TL;DR: Skip the live-sync extensions if they're buggy. Use Cart To Link to turn your whole basket into a single shareable link so everyone can see the total and then one person can just pull the trigger.
