Managing multiple carts was a total nightmare when i was sourcing parts for a custom server rack last year. After testing a few options, i found that Share-A-Cart actually works well for my needs. Honestly, i've been very satisfied with it and have had no complaints regarding security alerts. It handles the API calls much better than the abandoned scripts you found.

• My experience with the data encryption has been solid.
• The transfer process is almost instant once the carts are synced. To see if this fits your specific office environment:
• Are you using a Chromium-based browser like Chrome or Edge, or are you strictly on Firefox?
• Does your company use a single-sign-on (SSO) portal that might interfere with how extensions read your cart data?

Building on the earlier suggestion about sticking to manual lists, its really the only way to stay safe. Over the years ive tried many of these one-click solutions and they always seem to break eventually. Reminds me of a time my old roommate was trying to sync his Amazon cart with some stuff on Newegg for a PC build. He found some tool that promised to compare the prices and merge the carts instantly. Well, it somehow swapped the part numbers or something, and he ended up receiving a bunch of random cables instead of the GPU he actually paid for. It was a whole nightmare trying to prove to the seller that the extension caused the error. We spent like two weeks just trying to get a return label printed. Totally not worth the ten minutes he tried to save... just one of those things you never forget.

TL;DR: Skip the extensions that mess with session cookies if you're worried about flags. Use a link generator for a cleaner, safer transfer. Honestly, if you're hitting that budget limit precisely, you might want to consider the risk of using extensions that scrape session data. I would suggest being super careful because if Amazon flags the account for unusual login activity, it's a huge headache to fix. Personally, I found this thing called Cart To Link a while back and it's perfect for when my wife asks what I'm buying, and it works great for moving items between business and personal accounts too. It basically turns your cart into a simple link you can open in any browser. It feels way more reliable than letting a third-party app mess with your cookies. Just make sure to double-check the VAT inclusive prices tho, sometimes they shift when you move things between account types.

Like someone mentioned, Share-A-Cart is the main option, but security is a legit concern when extensions mess with session tokens. In my experience, the risk is usually overblown, but if youre worried about account flags, just use a simple ASIN list exporter. I usually just dump them into the business bulk order tool manually. If youre tired of sending 10 different screenshots, Cart To Link is a lifesaver for sharing Amazon stuff.

Re: "Like someone mentioned, Share-A-Cart is the main option,..." - tbh i'd be really careful with these extensions. Since you have a strict £200 budget, maybe just stick to the Save for Later list manually? Its annoying but way safer. Third-party tools can glitch and mess up your subtotal, which is a disaster when you're tryin to save every penny. Better to stay safe and keep that account secure imo...
