Craftsy is having a supplies sale right now with up to 70% off their quilting (and other crafty) fabrics and notions.
Last supplies sale they had I managed to pick up a few spools of Aurifil for just over $7. And they had some really cute Kaffe shot cotton bundles I know of that a few people I know picked up!
Head on over to Craftsy if you're in the market for a sale - it runs for only 3 days, 8/21-8/23.
Happy shopping!
