Though direct from Dyson, this is still the lowest price online.
Brad's Deals Editor David,
Get this brand new Dyson DC50 drops to $249.99 plus free shipping at Dyson. Plus shipping is free! This is the lowest price we found by $20. It features two-tier radial suction and has ball steering. Plus, you get to select three free tools in addition to the multi-angle brush and turbine tool that already come with the vacuum. This is part of a clearance sale at Dyson. Sales tax is charged in most states.
