Walmart offers the Munchkin Backseat Organizer, model no. 23215001, for $7.28. (Amazon charges Prime members the same with free shipping.) Choose in-store pickup to dodge the $4.97 shipping fee. That's tied with our mention from two weeks ago and the lowest total price we've seen. (It's a current best by $2.) It features three middle storage pockets and top and bottom mesh storage compartments.
