Honestly, its pretty disappointing that Amazon still hasnt added a native share button for the cart after all these years. Ive run into this exact issue when ordering supplies for my home office and it’s a total headache. Unfortunately, you arent missing some hidden feature... it just isnt a thing. The only official way is to move everything to a Wish List, but even then, it doesnt always keep the quantities right which is super annoying for a big project. I know you mentioned no plugins, but since youre on a tight deadline, you might have to look into the share Amazon Cart Extension because its basically the only way to get it done fast without losing your mind. Manual copying usually leads to issues and it just takes way too long. Let me know if you need help with the list settings. Good luck with the boss tomorrow, hope it goes well.
