Honestly, Walmart made this way more annoying than it needs to be. They used to have that share button right in the cart, but they pulled it a while back for some reason. So yeah, you arent crazy, the button is basically gone for most users now. Since you are on a budget and really need specific stuff, sending a link is out, but here is what I usually do when I have to deal with tech-illiterate family members:

• Take screenshots of the cart items clearly showing the exact brand and size
• Use the Walmart wishlist feature instead since you can share that link easily
• Just send her the direct product links via text or email if she is okay with clicking them Honestly, the wishlist is probably your best bet. You just add everything from your cart to a list, then hit the share icon at the top of that list. It gives you a link you can email to her. When she opens it, she can just hit add to cart from there. It keeps everything organized and stops her from buying the wrong version of something. It takes like two extra minutes to set up, but it saves so much headache later when you are trying to explain what to buy over the phone. Good luck with the birthday party prep!
