Quoted from ulmpharmd:My first clue to a shady buyer/seller is one that will not converse over the phone....call me old school, but I like to talk to a person with a transaction as large as most of these are (as the buyer or seller)
i have anxiety about talking on the phone to people i do not know. if i do this for a sale i must really want the game. having said that i have talked to multiple people over the phone about sales.
