Well, I have seen a few sales on this model since we have had ours. But, the best way to get it cheap is to earn Amazon Gift Cards through Swag Bucks searches and buy it that way. I also have friends who have purchased resale/remanufactured Dyson products through Amazon as well and they have had success. That is another option to try to get it cheaper.
Ordering was very straight forward on Overstock.com. Pricing on the refurbished model was attractive. Research on refurbished Dyson products suggested that buying refurbished was low risk - the difference is $ 150 and a 6 month vs. 3 year warranty. Delivery was ontime. Unit arrived in a plain corrugated box, definately the box used for shipping the new unit, but without any graphics. All parts, manuals were included. A single page of correspondance advised of the reduced warranty and cautioned that the dirt collector may be scratched (from previous use). No surprise on the warranty statement and the collector looked to be unused/brand new. In fact the entire unit showed zero use. Assembly took no more than 10 minutes. Have only used the vacuum twice, but an amazing amount of dirt was removed from what appeared to be a fairly clean carpet. I would reccomend the refurbished Dyson DC25.
