I go to equilter.com first and have used them for years. They are very fast and even with shipping included, their prices are comparable/lower than local especially since I mostly buy sale fabric. I love their scrap packs and have gotten them before, it all depends on if they have what you want to collect... it's the bolt ends and the pieces have always been what I would call usable sizes.

I'm usually looking for some pretty specific fabrics when I buy instead of use my stash, so my next stop is Amazon. Through them I've found Fields Fabric in Michigan -- right where the hubby is from. They seem to be a nice local all-around sewing store chain, the type that is disappearing from here and where I would shop if I had the choice
