Fabric Depot's web address is
www.fabricdepot.com - or you can just google "fabric depot".
Everyone should sign up to be on the mailing list, whether you live close or not. Every month they send out a flyer that shows what's on sale and when, and there are four 40% coupons, one for each week. You can use these coupons online. They're not like Joann's, either - if you want something that's already 20% off, but you want to use your coupon to get a better price, they'll charge you the full price and take the 40% off of that.
