Book early and your ticket to any city served by MegaBus might be as low as 1$. Of course only a few tickets are available at these low fares. These seats go fast, and an average fare for a Boston to NYC run may be around $20. Some passengers pay less, some pay more. Known as load balancing, everyone is doing it. Airlines started it, now hotels, cruises and buses are using computer programs to slowly raise a price based on the number of seats remaining. This is a great way to stretch your travel dollar. Another plus is that Megabus offers free WiFi. Not bad for a hundred pennies. www.Megabus.com
