I learned a long time ago not to get too excited about 50% off coupons at Joann's. I can't tell you how many times I have made a special trip to get a specific piece of fabric that I might use my coupon on, only to find that the fabric was already on sale or not eligible. I've learned to have the clerk scan it before they cut. Michael's is another store where coupons are deceiving. The funny thing is, I'm generally not a coupon clipper, but I love a bargain, especially at my favorite stores.
