Postal don't type in all caps. If you can't sell a card back it doesn't mean you can't enter. It just means you can't get your clintz back.
You said "There are people who don't want to waste cash on a game" well to the ones that do spend cash, its not wasting. Would it be right to say, there are people who don't want to waste money to buy you food? What if you went to a sporting event, and you saw a hot dog marked for 3dollars, but you know it is worth 1dollar, you haven't ate anything since 5am the other day. Would you buy it? Yes or no? Theres a two dollar difference would it be a waste?
