I'd urge to reconsider your stance on not pursuing recompense (or at very least reporting the seller) for the following reasons:
+ $13... dude - you could almost buy a Commander Class figure for that!

Also, it's not just the money, it's the principle IMO.
+ This seller relies on your inaction to survive. This time he's robbed you of $13... what's to say next time he won't rob someone else of $130 or $1300? Collectively this person could be making a lot of money through deceiving people.
