You said it all. It is a gimick to get us into the store. You can't get the coupon off a sale item even if you take it off the regular price - at least not here! I've tried. I used to buy a bold of muslin using the coupon since it rarely was ever on sale. I can't use that much fabric now, so that is not a good buy for me. You have to really read the label. For those cutter blades - go to Harbor Freight Tools and pick up your 45 mm blades for 2 blades for $1.49. That's the best deal around and they will work for you cutter. You will find them in the carpet tools section.
