Honestly, I totally get why you're looking for that. I went through the same thing last year planning a family reunion and kept clicking around everywhere trying to find a share button. Unfortunately, Amazon still doesnt have a direct shared cart feature where multiple people can just toss items into one checkout bucket. Its kinda annoying, but I guess it makes sense from a security standpoint... I am always super wary about sharing my login info or my Prime account details with anyone because you never know what could happen with your saved payment info or personal address if a bunch of people have access. The safest way I found to handle this is using the Lists feature. You can create a new list for the bachelorette party and click the Invite button to let your friends add or remove stuff. It is not a real cart, so everyone still has to move things to their own cart to pay, or one person has to buy it all at once. If you really need to just send the whole cart to one person so they can pay without any mistakes, I started using Cart To Link recently. It basically lets you turn the items you have picked out into a shareable link. It felt way more reliable than just copy-pasting links one by one. Just be careful to double check the quantities before anyone hits buy, but it definitely helps keep things organized without compromising your account safety.

No, Amazons backend architecture is weirdly restrictive. Youd think a tech giant would have real-time sync, but unfortunately their session tokens are tied strictly to individual UID logins. Its a letdown, tbh...

• Shared Lists are the only technical workaround.
• You gotta enable the invite to edit permission. Had issues with this for a project recently. Not as good as I expected.

Just saw this and had to jump in because I almost ruined a wedding shower doing this exact thing. Be careful if you try to just share a login, because Amazon gets super suspicious about multiple IPs logging in at once and they might lock the account right when you need to checkout... its a total nightmare to fix. Regarding what #2 said about "No, Amazons backend architecture is weirdly restrictive. Youd...", they are totally right. Since you cant actually share the cart, you really have to watch the costs. If everyone adds stuff to a list separately, you might end up paying way more in individual shipping fees than if one person just does a single bulk order. Make sure to double check if items are Prime-eligible too, because those non-Prime costs add up fast when you have ten different people picking things out. I would suggest using Cart To Link to keep things organized before you pull the trigger. I use it for all my group events now because it lets you bundle everything into a shareable link so everyone can see exactly what is being bought without the login chaos. Its a lifesaver for making sure you dont buy three sets of the same decorations by mistake. Just keep an eye on those limited time deals tho, because prices on Amazon fluctuate like crazy while you wait for everyone to agree on the supplies... seriously, things go out of stock so fast when you have a big group trying to decide.
