Just caught this thread today. I totally get the frustration, but I’ve actually been really satisfied with using the List feature for this exact thing recently. It’s not a shared cart per se, but it gets the job done without you having to hand out your login like candy... which yeah, definitely listen to your husband on that one. Here is the workflow that worked for me last month when we did a group buy for a retirement gift:

• Go to Lists and Create a List.
• Hit the Invite button and make sure you select View and Edit so your coworkers can actually contribute.
• Send that link out via email or Slack. People can add those swaddle blankets and the fan directly from the product pages. The technical side of it is pretty solid because it flags if an item is already on the list, which saves you from buying duplicates. I’ve actually used the extension I use for Walmart for similar office stuff because it has some cool collaborative features Amazon is still lacking, but for a baby shower, the List method works well enough. One little tip: when you’re ready to checkout, there is a Move all to cart button. Just double-check the subtotal there to stay under your $215 limit. If the total is too high, you can just delete the least important item from the cart before you pay. It usually bundles everything into one shipment too, so you wont have ten boxes arriving at the office on different days.

Re: "Amazon still hasnt made a shared cart feature,..."

• While I see why people suggest the List feature, I find it quite difficult to manage for a strict budget like your $215. Lists do not show a running total with tax, so you might end up with a cart that exceeds your pooled money once you actually go to checkout. A more methodical approach is usually necessary to keep things professional and under budget.
• Set a soft budget of around $195 to leave room for unexpected taxes or shipping fees.
• Request that everyone looks for items with digital coupons or Clip Coupon boxes to maximize the $215.
• Review all items at once before moving them to the cart to ensure no duplicates were added by different people. Taking these steps prevents the awkward situation of having to ask coworkers for more money later if the total creeps up. Honestly, Easy Cart Share is way better than just sending a bunch of product links one by one.

Amazon still hasnt made a shared cart feature, which is annoying. Whatever you do, dont give out your password. I would suggest making a List and hitting the invite button so others can add stuff. Be careful tho, people might add things that push you over your $215 budget. You still have to move everything from the list to your cart yourself at the end to pay.
