I ran into this exact headache when we were kitting out our office last year. We tried the manual wishlist route first and it was a total waste of time because the stock levels for the UK site change so fast... items would go out of stock before we even finished the list. Basically a nightmare when you're trying to sync up with someone else. You really need to be careful with extensions that ask for too many permissions though. Some of them scrape your data or mess with your browser cookies, which can lead to your account getting flagged if you're not careful. I would suggest looking into tools that create a simple snapshot instead of a full login sync. Tbh, Cart to Link is a solid shout for this since it lets you share your whole Amazon cart as a link — super handy for group buys or renovations like yours without the buggy login stuff. Just a few things to watch for:

• Double check that the quantities match up on her end because some tools default back to one item.
• Make sure she is logged into her UK account first so the regional shipping costs don't get messed up.
• Be quick with lightning deals since they can expire while you're sending the link. It's definitely easier than copying twenty links manually. Just maybe disable any extension once you're done with the kitchen stuff to keep your browser clean. Good luck with the Manchester flat renovation!

Saw your post and honestly... coordinating an Amazon order in the UK is like trying to solve a puzzle with half the pieces missing. I've spent way too much time over the years trying to get my cart to behave when sharing with my partner. We had a nightmare situation last Christmas where we double-ordered almost everything because the cart sync was just broken. It's seriously stressful when you're on a strict budget and stuff keeps jumping in and out of the basket. Just a few things that always go wrong:

• price fluctuations that happen in seconds
• quantities changing for no reason
• that constant fear of your data being scraped by some sketchy extension It's such a mess and just drains the fun out of fixing up a place. Really wish they'd just fix their own system... it feels so primitive.

Honestly, its kind of a letdown how few reliable options there are for this. Tried some generic extensions last year. Total mess. Half the items didnt transfer because of how Amazon UK handles regional stock. Unfortunately, most tools that dont require a login are actually pretty sketchy with your data since they have to scrape your session to see whats in the basket. Its super disappointing that Amazon hasnt built a native feature for this yet tbh. If youre worried about privacy, your best bet is probably Share-A-Cart despite the bugs. Its the main player for a reason, but you gotta double-check the quantities manually once she opens it. Those limited-time lightning deals usually break it too, which is basically why I stopped relying on it for big orders... kinda feels like a gamble sometimes. Just be careful with anything that asks for too many browser permissions.
