Walmart offers the Dirt Devil SimpliStik Stick Vacuum Cleaner, model no. SD20000RED, for $17.98. Opt for in-store pickup to dodge the $4.97 shipping fee. That's the lowest price we could find by $7. It features a 9" nozzle, bagless design, and can be converted into a hand vacuum.

Update: As a reader found, Amazon offers it for the same price with free shipping for prime members.
