VMInnovations offers the refurbished Shark Navigator Swivel Plus Upright Vacuum in Blue, model no. NV46, for $88.99. Coupon code "SWIVEL417" cuts it to $69. With free shipping, that's $50 under the best price we could find for a new one, although we saw a refurb for $3 less last September. It features brush roll on/off, a wide upholstery tool, dusting brush, and 5.5" crevice tool.

A 6-month warranty applies, although it's unclear who backs it.
