I was on a trip into Boston, the store is called, "The Hobby Bunker". Their website has the rule books and boxes of plastic figures, and they do alot of mail order.
However, suspect if you ask them about the figures in the plastic blister packs, and you know specifically what you're going to purchase, they'll likely go to the shelf, pull it if they have it, and send those along as well. Their customer service has always been very good.
They are probably the most extensive military miniature, brick and mortar hobby shop in the northeast, certainly in New England.
