Walmart offers the Copper Chef 2-Piece Copper Crisper for $7.58. Opt for in-store pickup to dodge the $5.99 shipping fee. That's the best deal today by $9 and within a few cents of our June mention, which was the lowest price we've seen. This dishwasher-safe crisper features a ceramic-coated nonstick basket and 10" x 13" cookie sheet.
