Amazon offers Prime members this Coleman Electric Quickpump, model no. 5999C120, for $14.01 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $5.58.) That's the lowest price we could find by $6, although we saw it for $2 less in July. It purports to inflate a standard queen-sized air mattress in under 60 seconds.
