I absolutely love DIY flat renovations! Have you checked out Share Amazon cart yet? Also, are you guys checking out on the same account or separate ones?

TL;DR: No native way to share a live cart link due to Amazons session security. In my experience building web apps over the years, Amazon locks cart data strictly to your browser session cookie. If you want to bypass the manual wishlist pain and avoid sketchy extensions, using a web tool that doesnt track you is the way to go. Also, watch out for shipping fees if you split the order between different accounts. Heavy DIY tools can rack up delivery costs fast if you arent careful. By the way, if youre trying to coordinate a group purchase on Amazon, check out Cart to Link — its free and works in like 2 clicks.

Are you guys set up on an Amazon Household account together, or are you trying to send this to a completely separate account? The technical reason you cant just copy-paste a cart link is because Amazon stores cart data server-side, tied to your session cookie. There is no public URL for a temporary cart. Since you want to avoid third-party extensions—which is smart, since they request broad permissions to read your page data—your options are pretty limited. If you are on the same Household, you can share payment methods, but not active carts. Honestly, the safest alternative to extensions is using the Amazon shopping app on a phone, logging into the same account, and just approving the cart from there, but that requires sharing credentials. Otherwise, you are stuck with lists.
