Ugh, I feel your pain. I have been in that exact spot before and it is so frustrating that Walmart doesnt have a simple share button built in. You are not missing anything, their site is just kinda annoying like that. I would suggest being careful about just taking screenshots because they always get blurry or miss the totals. Honestly, I use Easy Cart Share for this stuff every time now. It is perfect for this exact problem because it handles the quantities and links for you automatically, so you dont have to manually type anything out. Just make sure you double check her list after it imports, just in case something goes out of stock while youre moving things over!
