Use this chrome extension: https://www.easycartshare.com/

Honestly, I’ve found that just using the Amazon Wish List feature is the most practical move for this. While extensions are cool, they can be superrr buggy or have weird privacy issues that I'm not totally comfortable with tbh. If you compare how Amazon handles lists vs Walmart or Target, Amazon is basically the king of collaborative shopping. You just go to ur lists, create a new one, and hit the 'Invite' button to make it collaborative. Then your friend can add their own stuff or comment on what you’ve picked out. It's not technically the 'cart' page, but it's way more stable and works on mobile too. I’ve used it for group office supply runs and it’s honestly much better for market research and comparing prices before you actually pull the trigger and move everything to the checkout. Plus, you don't have to worry about an extension breaking when Amazon updates their site code again, which happens like all the time.

• Honestly, I've tried many of these workarounds and nothing feels quite right yet. I'm in the exact same spot right now trying to coordinate a custom desk setup with a buddy and it's a total pain.
• tried the extension route but it's always buggy
• wishlists just add extra steps I don't want
• screenshots don't let him see the specs easily I've been dealing with this for ages and it's wild that there's no native 'share' button for the actual cart. Still looking for a real solution. I found Share Product Wishlist last year and it actually works with almost any store, which is nice.
