I bought true wireless buds but dont have my receipt and one one works will I be able to exchange them

Yes they will exchange it

Yes they will let you exchange for another item may not give you cash back without receipt also you will need to show identification

Yes.

You can return most things to Walmart without a receipt. That's how they've always been. They stopped giving cash back a few years ago because some people really abused it, including shoplifting and then returning the item to the store for cash.

Beautifully put ma'am! That's exactly how they've always handled Mine. May God Bless You! 👸
