Dyson via Newegg offers the factory-refurbished Dyson DC40 Origin Multi-Floor Upright Vacuum Cleaner in Yellow for $149.99 with free shipping. That's tied with our expired mention from four days ago as the lowest total price we've seen for it in any condition. (It's also $248 under the best deal we could find for a new unit.) It features Dyson Ball steering, bagless collection, a 15-foot hose, and brush agitator.
A 6-month warranty applies, although it's unclear who provides it.
