I was out shopping for a Street and Trail bike (with no success) and while backing out of Bob Thomas Honda/Kawasaki I saw a sign for paintball air refills on a Marquee.
It turns out that there is a store pretty much right next to Bob Thomas called Compulsive Paintball. According to their sign, they are open from 2:30-6 M-F.

The guy at the store, Tony, said that all items in the store are the same as what is shown on the website. He was pretty cool about answering questions, they had a pretty wide variety of stuff, fill air for about a quarter an ounce. They had the new Vents goggles on display.
This is another good local source for people out that way. Headed east on Route 30 from the Route 48/Route 30 intersection, they are about 5 minutes or so. Pretty much right next door to Bob Thomas.
