What is Walmart's return policy if I don't have my receipt?

I know this is late, however, if someone else stumbles across this I would like them to know that the above answer is not correct. I am a manager at a Wal-Mart, and as long as you are within 15 days of purchase of the TV, (30 days for other electronics excluding GPS, cellphones, and media tablets which follow the 15 day rule, and 90 days for other products) you can return the item. You must bring in a valid ID, and you can only return an item without a recipet at Walmart three times a year. We key in your ID number for this purpose.

you can't return an item without a reciept
