REI offers the Eno Billow Air Lounge Inflatable Couch in several colors (Purple/Teal pictured) for $46.93. Pad your order over $50 to bag free shipping, or opt for in-store pickup. (Otherwise, shipping costs $5.99.) Excluding padding, that's tied with our June mention and the lowest price we could find by $13. (Most stores charge $80 or more.) When inflated, it measures 80" x 36" x 18" and includes a carry case.
