It's S.R. Harris fabric warehouse. The bargains were fabulous, but after the original owner sold it the bargains aren't as good. When you cut your fabric, you write the yardage and price/yd on a sticker that you place on the fabric. At checkout, they ring you up at 50% of the price that was on the bolt. I used to be able to get Timeless Treasure batiks for $5/yd there, but these days the bolt price is marked $14 so it tends to be $7. They sometimes have wide backing fabrics. Always check the coupons on their website before going, as the batik prices are better when they offer an extra-off coupon for batiks. I just haven't seen any for quite awhile.
It really is a warehouse, and they have every type of fabric you could ever imagine there -- not just cottons for quilting.
