How can multiple employees add items to one office Amazon cart?

My desk is literally covered in sticky notes from people in the design department asking for specific notebooks and it is driving me insane. We have about 12 people in our office here in Chicago and right now the system is just them emailing me links or telling me hey we need more coffee pods and then I have to spend my whole Friday morning manually searching for every single thing. It is such a massive time sink. I really need a way for everyone to just dump their stuff into one central Amazon cart so I can just review it and hit buy once a week.

I have been looking at a few ways to do this but I am torn on which path to take because I dont want to make it too complicated for the team.

• Option one is setting up a full Amazon Business account. I think they have something called Requisitions or some kind of multi-user setup where I can add people as members? It sounds official but I am worried it might be way too much setup for a tiny creative agency like ours. Is it actually free for small teams or am I gonna get hit with some hidden monthly fee?
• Option two is using some kind of third-party browser extension. I saw some mentioned online where people can just click a button and it sends the item to a master list. This seems easier for my team who are... lets just say not great with learning new software, but I worry about security and if those extensions actually work or just crash all the time.
• Then there is the bad option of just sharing the login for our main account with everyone. My boss would probably kill me for the security risk but it is technically the easiest way if people are honest about not buying personal stuff. But then I have to worry about people accidentally clearing the cart or checking out early.

I have a budget of basically zero for the software itself since we are already spending enough on the actual supplies. I really want to get this sorted before next Friday because we have a big project launch coming up and I wont have time to play personal shopper. Does anyone have experience with the Amazon Business setup for a small group or is there a better way to handle this without losing my mind...
