The new Oreos were spotted by The Impulsive Buy and may possibly be a Walmart exclusive. They come in 12.2-oz packages for $2.98. If you've looking to try them, you may want to call ahead as the Limited Edition Oreos tend not to be stocked at all locations. Update 6/2/14: The product has since been removed from the Walmart website but will be available at retailers nationwide starting Monday, June 9, 2014.
While the Reese's name brings a certain cachet to the new cookies, they appear to just be a mash-up of the already available Chocolate Creme Oreos and Peanut Butter Creme Oreos. Unless they managed to somehow infuse the peanut butter portion with actual Reese's crumbly peanut butter, I wouldn't get your hopes up. Nabisco also already makes Peanut Butter Oreo Fudge Cremes, which, with the fudge layer that covers them, seem more like an actual Reese's. I suppose they just couldn't resist pairing America's favorite cookie with America's favorite candy bar.
