Walmart offers the Intex Twin 8.75" Classic Downy Inflatable Airbed Mattress for $7.97. Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with last month's mention and the lowest price we could find by $8. It measures 39" x 75" x 8.75".
Reviewing this critical insurance policy takes a little effort, but it pays off big.
