Hi - I purchased a brand new wired Apple keyboard on eBay a week ago because my old one started to have some keys stop working. Upon receiving it, one of the letter keys does not register. The seller is being great and is offering me either a partial refund or a complete refund + return shipping; my choice. He mentioned I should be able to take the keyboard to an Apple Store and they would just replace it for free. Has anyone had experience with this? If that's true, I would rather bring in my old keyboard for a replacement and return this one. Thanks!
