As one of its daily deals, Kmart offers the Northwest Territory Anti-Gravity Suspension Lounger, model no. 80010300147, for $42.99. Opt for in-store pickup to dodge the $17.14 shipping fee. That's $27 off and the lowest total price we could find, although we saw it for $3 less last week. It features a dual finger-tip control system and threaded bungee system. Deal ends today.
