WalMart now is tougher on returns than Target! At least mine is! They used to take things back, no questions asked. Well, I had to return a carseat I bought, couldn't find the receipt. I had not even opened the box. I brought my credit card bill with the purchase listed on it because I didn't have the receipt. They couldn't look it up based on the card I paid with (which Target can do in seconds). They wanted to know what day and time I made the purchase AND which checkout lane I went through!! It was crazy. They ended up giving me a gift card because they couldn't credit my card since I didn't have my receipt. Lesson learned. Wal Mart's return policy stinks now! (and I found the @^!%@$ receipt a few days later at home! I knew I had it somewhere!)
Apparently their policies vary by store. My WM would have taken the seat back, no questions asked. You would have received a gift card, not cash (but if you'd taken it back 12 months ago, you'd get cash!) I guess mine is pretty loose!
