I don't mean this in a dicky way, but I'm wondering how someone can "pressure you" to sell something that you're
only getting $1 for? Even if you had fifty or so games, that's not exactly a high dollar transaction at a buck each. Were you in a really difficult position where you needed cash immediately? If so, it's understandable and you shouldn't beat yourself up over it much. Chock it up as a lessen learned. Regardless, you shouldn't allow yourself to be pressured
that easily, and you should always research what you can get for things before you offload them. Even if you were desperate for cash at the time, selling one less game for a dollar wouldn't have hurt your situation anyway, and had to have been worth the wait.
When you're in a pinch and you fire sell things to move them quickly, put them up for half of what they go for, not 2% of what they do.
