Is there actually a way to share a live grocery cart with a roommate without sharing passwords or having the app crash every five seconds? I’ve been using delivery apps since like 2018 so I know my way around the UI and the usual account settings but this is driving me crazy.

My new roommate and I just moved into a apartment in North Austin and we’re trying to keep our grocery budget under $450 a month by doing one big weekly order instead of five small ones. The problem is that every time I try to build the cart on my phone he wants to add stuff like his specific brand of organic kale or whatever but there’s no collaborate button. I tried the family profile thing on Amazon and Whole Foods but that just shares the Prime benefits and the credit card info it doesn’t let us both see the same basket in real time.

Its super urgent because we need to get this order in by tonight so we have food for the weekend and the delivery slots are filling up fast. I even tried just giving him my login info so he could log in on his phone but the app keeps getting confused when we both have it open at the same time. One of us adds bread and then the other person refreshes and the bread is gone but the milk is there and then half the cart just disappears into the void. It’s like the session tokens or the cache is fighting itself or something and its basically impossible to keep track of what is actually in the basket.

Are there any specific apps or maybe a third party tool that lets you sync a cart across two accounts? Or a workaround that isn’t just texting a list and me manually searching for every single item? We’re looking for something that works with the major chains like H-E-B or even Walmart. I’ve looked into stuff like AnyList but that’s just a list maker it doesn’t actually put the items in the store cart for checkout. If I have to type in low fat greek yogurt one more time only for it to be the wrong brand I might actually lose it. How do people do this without it being a total headache...
