Need some art supplies? There’s a 30-percent-off coupon for one non-sale item (time to buy that expensive one thing) in today’s Philadelphia Inquirer, Section B, page 7, for the new art supply store in town, Blick Art Materials, which is having a grand opening sale through Sept. 7. There are prizes listed in the ad besides the coupon–all most appealing if you ask me. The store is at 1330 Chestnut Street, lower level.
