I might not be of any help, but here's what I was able to dig up:
http://www.fabric.com/ -- has some fabrics for under 1.95/yard, shipping for 3 yards of a random fabric was $4
https://www.fabricmartfabrics.com -- had a bunch of fabrics, but requires you to sign in to checkout, so i couldn't check shipping.
https://www.fashionfabricsclub.com
-- Most fabrics looked like they were about 5-ish/yard. Shipping for purchases under $25 is $7

We have a mill-end fabrics down here in carson, too. I didn't think their prices were terrible last time i went there. (though, i didn't buy much and it was a long time ago, so don't quote me. >_>; )
