If Walmart won't take them as a return you could always take them to Cabelas or Bass Pro and trade them in for store credit! lol
Been to Walmart a coupe of times. Didn't seem too bad, but it was hard to find stuff. My wife doesn't like it and she does most of the shopping so that's that. She says the people are kind of rude, the shoppers, not the staff. And she doesn't like that they force you to use plastic bags.
Good information here. Also, if there is freight damage to the item, Walmart will see it first. There is nothing more galling than to be told that YOU were the party that damaged the product. This happens quite a bit when the RECEIVER initiates the freight damage claim.
