I only get end-of-bolt discounts when I ask ... which is wrong, wrong, wrong ... I shouldn't have to ask! Furthermore, most of my coupons end up in my trash because invariably the fabric is all marked down (a bit) during the same dates the coupons are valid. Since I already have quite a large supply of rotary cutter blades and machine needles, etc., unless I can find someone to give my coupons to, they are a waste of paper.
I get lucky sometimes at the Red Tag table; sometimes they have some of their most expensive, highest quality 100% cotton there and if I have a 10, 15 or 20% off total purchase coupon and also an end-of-bolt discount, I walk out of there feeling lucky and patting myself on the back.
For those of you who do machine embroidery or anything that requires stabilizers, those coupons are good for buying stabilizer. (I buy the whole bolt.)
