Amazon offers the Oreo Mega Stuf Chocolate Cookies 13.2-oz. Pack for $2.98. Clip the 20% off coupon on the product page to drop it to $2.38 at final checkout. Plus, Prime members bag free shipping. (Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping costs $7.13.) That's tied with our mention from two weeks ago and about a buck less than you could expect to pay in local stores.
