Hancock's of Paducah's web sale fabric section - this is first quality fabric sold at anywhere from $4 to $7 per yard because it is from one or a couple of seasons ago. You won't find whole lines of things like Moda Marbles blenders, but you will find tons of really nice fabric that gets "refreshed" pretty often. If you allow yourself to be put on their emailing list you will also be notified about specific promotions that help even more (like the rare and coveted "free shipping" days...or the even better "additional 20% off entire order" sales).
Much of my stash arrived in bright yellow plastic Hancock's of Paducah mailing pouches!
