No. Greyhound tickets are only sold by Greyhound and its affiliates through its website, Greyhound.com, its 800# or in its terminals and agency locations. We do not sell tickets on Craigslist. I would be wary of any such offers being advertised on Craigslist because the ticket is most likely fraudulent and will not be accepted for travel.
