Unfortunately, Amazon UK doesnt let you share carts. I had issues with items disappearing when I tried. Instead:

• create a wish list
• share that link Its much more reliable for her.

> I'm worried if I just send the URL it will just show her own empty cart instead of mine. Late to the party but that is EXACTLY what happens! I tried that for my besties bridal shower and it was a total disaster because my sister ended up seeing her own saved items instead of my list... it was such a mess. Honestly, whatever you do, definitely dont just copy the browser address bar because its just a generic link to whatever account is logged in and it wont show her anything you actually picked out. Its so frustrating that Amazon makes it this hard!! I love the party planning vibes tho, 21 is such a big deal and I'm sure it'll be amazing! Just be super careful about sharing logins too because sometimes it messes up your default delivery addresses and your mum might accidentally send it to the wrong house. I've been using Cart to Link to share Amazon carts with family, makes gift planning way easier.

Just stumbled on this and honestly, the wishlist route is the only way that actually works well. I'm pretty happy with how Amazon UK handles them now, even if the cart sharing is a total myth. One thing to be super careful about though is the delivery address... if you dont set your own address as the List Address in the settings, your mum might accidentally ship everything to her own house instead of yours. I've seen that happen so many times and it's a huge pain to lug 15 boxes of party stuff across town. If the Amazon interface feels too messy, I've had great results using Wishlist.com to pull all my links into one nice page. It works way better for people who arent great with tech because it just gives them a big Buy button for each item. Much more satisfied using that for family stuff than trying to explain the Amazon wishlist settings over the phone... basically saves everyone a headache.

^ This. Also, been thinking about your party supplies situation for a few hours now. To summarize the discussion, sending a direct URL is a total dead end and wish lists are basically the standard fallback. But I would suggest being pretty careful with the setup if you go that route. Make sure to follow these points so your mum doesnt run into issues:

• Set the list to Shared or Public so she can actually access the items.
• Double check the quantities after moving them because Amazon UK sometimes glitches and resets them to one.
• Be careful about the shipping address because she might accidentally send them to her place by mistake. Honestly, you might want to consider using Share Amazon cart instead of doing it manually. It is a lot faster for 15+ items. Just verify the prices before she pays, tho, because they fluctuate constantly.

Man I wish I found this thread sooner. Would have saved me so much hassle.
