There are two places I like to purchase fabric where the prices are really discounted. I prefer to purchase good quality quilting fabric, but cannot afford the full prices. I'm always looking for discontinued, sale or clearance buys.
My first favorite place is The Stitch-N-Frame shop located in Vicksburg, MS. www.stitch-n-frame.net
Every Wednesday, she posts the "Thursday Special" with many different fabrics marked down. Those specials are good Wed. evening, all day Thursday and early Friday until she turns it off when the store opens.
Every Thursday, the specials change. In addition, she frequently has Fall Specials or Thanksgiving Specials, etc. They are wonderful to deal with and great with shipping. If you tell them you need something asap, it comes fast.
My second favorite place is Whittle's Fabrics in Smith's Grove, KY. www.whittlesfabrics.com
Many of their fabrics are discontinued, but hey, they have name brand quilting fabric and not the cheaper fabrics in the big box stores. If you live close enough to actually visit, the fabric is even cheaper. I've bought Marcus Bros. fabric for as little as $3 per yard.
Finally, I've recently ordered from www.fabricandetc.com which is a quilt shop going out of business. Her items are currently 40% off. I bought 10 sets of Moda charm packs for $4 apiece.
