Last year I won an auction for a GPS unit. Paid via Paypal and then waited for delivery. After a week, I contacted the guy who gave a story about it being the holidays and he didn't get to the post office . . . so I cut him some slack. A few more days and he doesn't respond to e-mails requesting a tracking number, which he says he's getting . .

Long story, short . . . he didn't have a unit to sell . . . PayPal gets involved, refunds 100% back to me, meanwhile the price of the GPS falls like a rock and I end up buying it direct from the maker with savings galore.
