I am so lost right now trying to figure out this whole wishlist thing for my sisters baby shower next month. Shes in Orlando and I am trying to get everything organized from a few hours away so I started using the Walmart app because its what I know and I thought it would be easiest for everyone to just go to one store. But now I am seeing cute stuff on other sites like Etsy and even some random local shops that dont have big websites and I cant figure out how to add them to the Walmart list.

I keep hearing people talk about these universal wishlist tools but I honestly dont even know what that means or how they work like is it just one big list for everything or do I need to download something else? The Walmart app is okay but it feels kinda clunky if I want to add something that isnt actually sold by them. My budget is pretty tight since I am paying for the decorations and food too so I need to find the best deals across different stores without making ten different accounts.

Sorry if this is a really basic question but are those universal tools actually better and more flexible than just sticking to the Walmart app or is it gonna be too complicated for my older relatives to use? Does it let you put literally anything on there or do I have to stick to certain partners?...
