TL;DR: Sadly there is no one-click button to merge them directly between two separate accounts, but using the list feature is the absolute best workaround! I totally feel your pain because I do this constantly! Just a few months ago I was trying to kit out my entire new home studio with lights and soundproofing while also ordering bulk supplies for a huge community event I was running... talk about stress!! I had tabs open everywhere and kept losing track of what was where. Honestly, the easiest way to handle this mess is to just move everything from one cart into a Wishlist, make that list public or shared, and then open it on your other account to add them all at once. It is so much faster than searching for every single item again! If you are doing this often for your job you should definitely check out Amazon Business. I switched over to using their business features for my freelance work and it is seriously a game changer for keeping things organized. You cant go wrong with any of their multi-user tools tbh. It makes the whole checkout process way less of a headache when you have to separate personal stuff from professional expenses. Just get their business setup and you will thank yourself later! I love how much time it saves me every single month now. Its way better than trying to do it manually every time. It made my life so much easier when I was ordering those specialty mic stands last month!

Just saw this. I was skeptical about security but tried share Amazon Cart Extension. It safely bundles items into a single link so you wont have to re-add everything manually.

Saw this earlier and just had to jump in because I have been doing this for years! It is absolutely amazing how much time you can save once you get a proper workflow down for these big orders. Managing separate personal and work carts used to be a total nightmare for me until I started using the list trick combined with a specific cost-saving strategy. ngl it used to drive me crazy... Here is the most professional and methodical way to handle this without losing your mind:

• Create a Public Wish List on your secondary account. Move every single item from that cart into this specific list. It is a fantastic way to keep everything organized and ensures you dont miss a single item!
• Log into your primary account and search for that public list. You can then use the Add all to cart button which is a total lifesaver. This avoids the manual search-and-add grind entirely!
• Always verify if your work items qualify for Amazon Business pricing before merging. Sometimes keeping them separate actually saves the company money because of those bulk discounts.
• Check the shipping thresholds. Consolidating everything into one cart often hits that free shipping minimum way faster, especially for non-Prime items! I love using this method because its clean, secure, and keeps my receipts perfectly organized for reimbursement later. It is a total game changer for big shopping nights! Honestly, once you do it this way, you wont ever go back to the old manual way... basically it just works every time.
