Dear Ms. Brancato,
Allow me to introduce myself. My name is Fred Eldridge, and I work with New England Ex-press Bus Carriers. We are a full service express transportation provider operating in the north-eastern United States and southeastern Canada. We have chosen to contact you because our records indicate that you are a frequent traveler in the region. I believe you will be able to appre-ciate the benefits of bus travel.
Traveling by bus simply makes good sense. For instance, you can spend your next journey from Montreal to Boston in one of our ultra-comfortable coaches for only $34.50 round trip. That's less than a third of the cost of the average plane ticket, without all the check-in hassles and flight delays. And with today's high gas prices and dangerous wintertime road conditions, why take your car? Leave the driving to us instead!
So, when your future plans call for regional travel, contact New England Express Bus Carriers and let us show you what we can do for you!
