Nothing beats free travel, which is what megabus.com provides with a 2000-seat giveaway on routes between Boston and three Northeast cities.

This deal celebrates the expansion of megabus.com service to and from Boston. Starting Aug. 17 from gate 12 in South Station, megabus.com will boast two daily departures to Burlington, Vt., as well as four daily departures to New Haven, Conn., and Hartford, Conn.

One thousand free tickets are available on each of the two routes. When those are gone, a limited number of $1 seats will also be available. 

Note: There is a $0.50 per transaction booking fee.
