As one of its daily deals, Best Buy via eBay offers the Dyson Ball Multi-Floor Upright Vacuum Cleaner for $199.99 with free shipping. (Amazon charges the same price.) That's tied with our mention from three weeks ago and the lowest price we could find by $164. It features radial root cyclone technology, a HEPA filter, self-adjusting cleaner head, reconfigured brush bar, and 35-foot cord. Deal ends today.
