I bought a air mattress from Walmart but I don't have the box and I lost my receipt can I still return them??

To be sure why don't you call customer service and ask them.

Knowing Walmart I doubt it

All you can do is try

As long as you have a valid picture ID, you should be able to return it.

Maybe you will get store credit, it is worth a try.

Tell them it was a gift and You don't have a receipt

Depends how long you have had this and if there is a manufacturer warrenty.

i believeif you have the serial number you should be fine. talk to the manager

Not sure, unless these is a label with numbers I doubt it.
