I know of a place in Claremont New Hampshire that sells fabric $2.65/yard if you buy 100 yards. Lots of quilting fabrics and calicos. He does not have a website, but if you're looking for something specific he can email pictures to you. I have bought from him several times and the quality has always been great. Shipping was extremely fast, too.
