How do i make returns easy in walmart?

By not shopping there.

Just have your receipt, I suppose. I’ve never actually had any trouble returning anything at Walmart.

Maybe this will help?

i return things all the time in walmart (i buy a lot in walmart, that’s why) and i often don’t have the receipt. i never ever have a problem. as long as you have something with a bar code, they don’t care if it’s open or whatever. the only thing is you can’t return cosmetics, which is logical, and of course, probably not underwear. other than that, they are great about returns, i find.
