Here's a link from my bookmarks, I keep it there so I don't have to go looking.
http://www.quiltingboard.com/posts/list/4728.page and don't forget about five bucks a yard, bu google it, because everytime I type it I end up somewhere in a dead link.
Oh and my current favorite is
http://desperatequilters.com/ for anything name brand (like Moda) for less money, and if you're looking for specifics, they are great at having lots and lots.
