Check the third party shipping box first. Last year my uncle nearly paid double for shipping because I forgot it, but the app link usually works fastest for groups tho.

TL;DR: Use the Send list to others button and pick View Only for a static URL. I dealt with this last year. The collab links use a different token structure that forces auth. I found that the guest view link bypasses most login requirements because it doesnt need write access to the database. It basically generates a public-facing static version of the list. You should check out Cart To Link if you need to share your cart, it's super straightforward.

Totally agree with the first reply about the View Only link. Its the most stable way to do it natively. One thing to watch out for tho... if the list is set to Private in the settings, those invite links can still trigger a login screen on some mobile browsers. I usually just toggle the list to Public for a few days to make sure the uncles in Chicago dont have to deal with password resets lol. Actually, Cart To Link works great for this—no more copy-pasting individual product links or worrying about Amazons weird session cookies. It basically creates a cleaner landing page that just works for everyone without the login loop. TL;DR: Set list to Public first, then use the View Only link to bypass the auth requirement. Or just use a third-party tool to skip the Amazon headache entirely.
