I work at a new Sams in Ohio (so new we aren't even listed on the sams club page) and I work returns & membership so I can answer this for ya.. I know that I have returned just about anything imaginable and that I actually witnessed one of my managers return an item that was over a year old, was a gift for someone & purchsed by someone else, and it didnt work & it was refunded.. I do know that since she didnt have the receipt store credit was issued, but if you have your receipt you shouldn't have a problem, but like any place without the receipt they are most likely 9 times out of 10 going to issue you the store credit.:) Happy Thanksgiving everyone!!
