I just came across this, thought it might be of interest to the ppl here who take fung wah/lucky star/bolt bus.
Later this month, a new discount bus service will start serving Boston-New Haven, Boston-Philadelphia, and Harvard Square-NYC.
See http://transportazumah.com/ for schedules and to make a reservation. Use the discount code CRAZYFARES to get fares as low as $2 each way. The undiscounted fares are $20, $40, and $20 respectively.
