Reynolds Kitchens site they currently have available a coupon for $1.00 off parchment paper, which is great for evenly baked cookies that don't stick to the sheet and super-fast clean up.
Here is a link to the coupon, which is good until 7/23/12 on Reynold's site

Depending on where you live/shop the cost is between $3-$5 for a roll. The coupon link also has a recipe for Crisp & Crunchy Sugar Cookies below the coupon, or if you are not interested in that you can stop the print after the coupon itself is printed, which is what I usually do on coupons to save ink.

For either coupon, you will need to enter your name and e-mail address to get the coupon.
