Walmart offers the Intex Classic Downy Full Airbed, model no. 68758WL, for $8.88. Opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with our mention from a week ago as the best price we've seen for a full airbed. (It's a current low by $7.) It features a 2-in-1 valve and plush flocking.
