Im really confused about how this walmart pickup thing works and Im super stressed about it because I have to get my groceries done by tomorrow night or my kids will have nothing for school lunches. My budget is strictly $150 this week and Im really trying to stick to it so I dont overdraw. My sister is trying to help me from her house because she has better internet than me but I dont know if we can both look at the same cart at the same time? Like if she adds milk can I see it on my phone right away or is it just a one-time link thing? I sent her the link but it looks like a dead page on her end or something. Im so sorry if this is a dumb question but I just have no idea where to start and I dont want to accidentally buy everything twice and spend $300 by mistake.

Here is what I am trying to figure out:

• can we both add stuff at the exact same time
• do we have to use the same login or is the link enough
• will it show me if she changes the brand of something I picked
• does the link expire after a few hours

Im just really worried Im gonna mess this up and end up at the store with no food because I didnt click the right thing. Has anyone actually done this before without it breaking?
