I saw the regular Klymit Static V sleeping pads on sale this weekend at Sam's Club (Store #6346).
This is probably the lowest I've seen these go. They are great budget air sleeping pads, I have no trouble sleeping on my sides with them. They don't have a lot of insulation (R value) so it's good for camping in the warmer weathers.
