What do I do if I got rather expensive air matress and when we blew it up it wouldn't hold air. Was a gift, we don't have receipt, just box and everything that came in it.

Sometimes they will only give you a gift card.

They'll exchange it but bring it in the box and everything that came with it. Need DRIVER'S license

They will exchange it with drivers license. Occasionally you may get a supervisor to approve a refund

I don't know about Wal-Mart but academy let me return mine for the same reason

Unless the policy has changed, air mattress issues must be handled through the manufacturer. Walmart does not issue refunds on air mattresses. You might be able to exchange it for the EXACT same one. This was the last policy I was aware of. I'm an employee.

You might be able to exchange it . Just take it to the service desk and explain the situation.

Take it back and get a gift card. You can even exchange it if you plan on keeping it.
