Evan,
I had the same thing happen to me about a year ago. It took several attempts haggling with PayPal to get a refund, but I finally did. I talked to USPS and they said this is a common scam. The seller apparently makes a bunch of sales, gets one tracking number which is sent to all of the buyers, but the tracking number is only for a single address. So, someone actually gets a package, but all of the others get screwed. My local USPS office took a photo of the package with the tracking number and someone else's address. I emailed that photo to PayPal and that finally convinced them.
Good luck
Ted
