Amazon offers Prime members the Oreo Chocolate Sandwich Cookies 14.3-oz. Bag for $2.98. Clip the 20% off coupon on the product page to cut the price to $2.38. With free shipping, that's tied with our mention from two weeks ago and about a buck below what you'd pay in-store locally. (Non-members can spend $35 to qualify for free shipping; otherwise, it adds $7.20.)
