Possible gift card,. best guess.
So anytime I have returned if you paid by a card and have no receipt they'll look it up, I don't know about returning if you paid with cash. Also here is this info: Standard Returns As part of our COVID-19 response, we will temporarily not allow store returns on certain items. For the most up-to-date information, please visit Walmart's Policies and Guidelines website. Hope this helps!
