The only Black Friday sale I hit is Joann's. They have all quilting and sewing notions on sale at 50% off (they have for the past several years, anyhow), plus there's a coupon for an extra 20% off. I buy what I need for the year in needles, rulers, basting spray, buttons, zippers, velcro, pins, etc. at a significant savings. They will also sometimes has a loss leader item like a serger or machine, but maybe only one or two per store, if that. I try to stay away from the cutting counter on that day --- some of those ladies can be brutal about getting in line to have 1 yard of each of the bolts in their three cartfuls cut.
