I'm basically a noob to Craigslist, but since it's free, I decided to give it a shot, and posted an older minivan there. We were looking to upgrade, and the dealer was low-balling us on the trade in, so I'm trying for the private sale. Price is $4000. Should I insist on cash only? Since cashier's checks and money orders can be forged, cash is the only safe method, right? Experienced Ebayers/Craigslist users, what do you usually insist on for payment, especially of larger amounts? Is cash only common? Thanks in advance.
