Story time. Asked the people if they had any video games they wanted to sell. We talk for a minute and they tell me to come back in half an hour they'll pull them out. So I comeback and the guy is walking outside with an NES and a bunch of games. Meet him at the table and notice a girl with a Pokemon shirt on looking at the NES games that are already out. Guy tells me they're his son's games who lives in Seattle(im in Baltimore)and he needs to ask him if he can sell them, but to make him an offer. I go low at $25 and the Pokemon girl says some of these games are worth more than $30 each. Then she takes a stack of the games and says id advise you not to sell these games for under $100. Lady running the sale tells her thanks for coming to look at them. These mofo's called an expert in on me,felt like Pawn Stars. Still left my number for when they get a hold of their son.
Better just to leave your phone number from the get-go in a situation like that; chances are if the yard seller has to make a "consultation" the other party won't decide to make the sale and you're wasting your time.
