Yo! You are gonna love this because I had the exact same issue last summer. Amazon makes it way too hard to do this normally!! You absolutely need to use Share-A-Cart. It is a total game changer for desert trips or any group gear hauls. I use it constantly! Basically you just install the browser extension and it gives you a simple link to send your friend. They click it and every single item pops right into their cart instantly. Its amazing because you dont have to worry about public wishlists or any of that slow manual stuff. It works like a charm for 15+ items too. Its honestly the only way to do it without losing your mind... definitely try it out before you head out next weekend!
