Honestly, Walmart is so annoying with this. They dont have a direct button, so I would suggest making a custom Registry instead. It sounds weird for a camping trip but it works way better than basic lists. Be careful though, make sure to set it to public so your friend can see everything, like that $5 Great Value Trail Mix. Using a shared link is way safer than giving out your login info.

Just saw this and I am so excited for your Ozarks trip! To keep your budget safe, definitely use the Walmart Lists feature instead of the cart! You just make a list, add everything, and share the link. Its a fantastic way to track costs together without sharing passwords! Super reliable and makes coordinating snacks so much easier!

Just caught up on this and I've gotta ask... are you guys using the mobile app or the desktop site? In my experience, the API calls for the cart behave totally differently depending on the platform, and it changes which workaround actually sticks. Over the years I've tried many methods to bypass their clunky UI, and if you're looking to save money, stick to the Great Value 30oz Honey Roasted Peanuts for $5.44 instead of the smaller tins. The unit price is way better for a group. Walmart's session handling is notoriously buggy when it comes to shared lists though, so be careful if you're both adding stuff at once. Honestly, Easy Cart Share makes it so much faster to transfer a cart between different accounts.
