There must be hundreds of those. Each deal has it's own thread. Anything in particular you're looking for ?
Well, I bought a pack of AAA batteries on Amazon, opened it, and they are all corroded. So I want to get a refund. Of course.
Anyways, the only thing I see on their site is to return it, but I don't want to pay shipping. Is there a way to start a case about a defective item?
