tell them their made in china bull$&!# needs to go back where it came from and you want your money back or you're gonna sue. j/k
those places rarely question a exchange for the same product. tell them you got a dud and you would like to swap it for a winner.
the one personal exception i can think of actually happened at lowes... i bought a li-ion dremel that was mispriced. they honered the price at the register. sweet! get home and it doesn't work. bummer! when i tried to exchange it for another that worked, the ASM stood by her overinflated ego powertrip lack of common sense decision to only offer me a refund at the original purchase price. woman, i bought the thing 30min ago, its not my fault your employees mislabled the product and i got lucky. i wouldn't have bought the thing had they not mislabled it. im now wasting my time, transportation money and blood pressure because you enjoy playing napoleon. long story short, she was having some sort of psycological issue and the general manager gladly exchanged it for a new item the next day when he was in..
