I have read on some threads that say they won't trade with people that have so few trades. I don't think most would worry about it.
I have made a deal with a person ,agreed on price ,place to meet and time. Texted the day of the meet while getting ready to make the 2 hour drive. I was told “oh I sold it last night”. No sorry or anything.
Has this happen once. About a 3 hour drive, and seller refused to drive past the end of his driveway. Had the balls to say if was "first come first serve, and the other guy got there first"
