I don't expect people to keep every game they buy. Sometimes you buy/trade for a few because you only wanted one. Sometimes a operator or warehouse calls you to offload stuff, or you find a hidden gem that nobody else knew about. Stuff like that doesn't bother me at all. I don't even hold anything against the guys that buy games as their business for the sake of fixing them up and re-selling at a later point.

But there's a few scenarios that drive people nuts. We've all seen them, been on the losing end of them, or got priced out of the market because of them.

Typically it's a good deal on a game that's just a few hours away. You contact the seller, you're first in line, you agree on a price. "I'll be there in 3 hours with cash, definitely buying the game" you tell them. Everything seems all happy and all parties are in agreement. By the time you arrive, some flipper has already swooped in and the game is gone. Now you've spend half a day driving, burned a few bucks in gas..... and the next day you see the same game on pinside, or facebook, or craigslist with a big markup. Sometimes with the same pictures as the original sale, because they can't be bothered to even set it up for good pictures.

Or another fun one. You see a game for sale at a show for a good price, and you call right away to buy it. But because you're just a "regular admission", and not a vendor, it's already been claimed by somebody else before the show even started. Funny thing is... the next day the game is still in the SAME SPOT, but a new name/number on the tag with a hefty price increase.
