People are selling 5 days left from their 10 day tickets or 2 days left from their 7 day tickets. I thought you're finger scanned and aren't able to use someone else's tickets. There are tons like that for sale. How does it work? Also, I'm a little afraid to buy something on ebay however it says you're guaranteed if you use paypal. Would you get your money back if a sale was a scam?

Can someone leadme in the right direction? Thanks!
