Safe Trade

Don't Be Fooled

  • When selling, do not put your home address in your ad.
  • To avoid scams, buy and sell with people you can meet locally, in person.
  • When meeting with someone you don't know, meet in a public place. If that's not possible, have a buddy with you. Also, carry a cell phone; if you feel unsafe, you can call a trusted friend, and stay on the line.
  • Never give out financial or private information like account numbers, PayPal login, or social security number.
  • If an offer sounds too good to be true, it is. Walk away!
