Ugh, honestly I tried doing the same thing for my sisters shower and it was way more of a headache than I expected. Most of these universal apps claim they sync perfectly with Walmart but then the prices dont update or items go out of stock without any warning. Its kinda disappointing when guests show up to the store and find nothing on the shelf because the app lagged. You also gotta watch out for those sneaky transaction fees if you try to do a honeymoon fund or cash registry on the side. Are your older relatives actually going to the physical Walmart store to buy stuff or are they tech-savvy enough to order online? And are you looking for something that allows group gifting for the more expensive items? If you want a decent layout despite the sync glitches, Joy is worth a look tho it still has its quirks.

Honestly, the most reliable way to handle this is using a universal registry platform like MyRegistry or Babylist. Both allow you to import your existing Amazon and Walmart lists so your guests only have to visit one link. MyRegistry is a decent option if you're worried about technical glitches because their sync tool is pretty established and conservative in how it handles data. It's a methodical process where you just link the store accounts. It works well for older relatives too since the interface is fairly standard. You just need to make sure you've set the permissions correctly on the Walmart side so the app can actually see your items. I found Share Product a few months ago and it's definitely the best tool for making quick wishlists.

I used Zola for my wedding last year because it was free and simple. Actually found a really useful browser extension that lets you just pin items from Amazon or Walmart right onto your main list using their bookmarklet tool... it works surprisingly well.

• Updates price changes so guests dont overpay
