How the heck do I share a single shopping list with my whole family so they actually see it? My sisters wedding is in like two weeks and everyone is asking what to get her but I am losing my mind trying to organize it.

I saw people talking about Elfster but that seems more for secret santa stuff and not just a general list for a wedding gift pool plus it feels weirdly formal. I also tried just sharing an Amazon list link but my aunt in Florida says she cant open it without a login and half my family is tech-illiterate lol. Is there something that lets me add stuff from different stores like Target and local shops without making people sign up for stuff...
