Sears offers the All Power America Foot Pump Inflator with Air Gauge in Red, model no. APT2580, for $6.99. Plus, Shop Your Way Max members bag free shipping. (Not a member? It's free to sign up for a 90-day trial; otherwise, shipping adds $6.50. Free in-store pickup is also available.) That's the lowest total price we could find by $3, although we saw it with pickup for $4 less last summer. It features a universal valve adapter.
