I'm trying to plan a day trip to NYC for either February 18 or February 25. I would be taking a bus from Baltimore and returning on the same day. I know this sounds crazy, but I'd like to find something in the $15-$20 range, or possibly less. I know that Bolt and Megabus have offered $1 or less seats--one time I even took a bus up and back for 50¢ because of a promo code for Megabus. Does anyone know of any promo codes for any bus services, or of any systematic way to get the $1 seats that Bolt and Megabus claim to offer?
