Online retailer Ebuyer has put the Dell 3330DN mono duplex network printer back on sale for £175 with ample stock available.
Not only is this by far the cheapest price you can get the 3330DN for but it also comes with a combined cashback offer of £175 which essentially gets you the printer for free.
The only requirement is that you have another (old) laser printer to trade-in (you might even get one from eBay). Ebuyer has also ready confirmed that Dell will honour both the cashback and the trade-in. Unfortunately, there's no free three years warranty or a free Ricoh Aficio all-in-one laser printer on offer.
The printer is a very capable one. It is a duplex network ready model that can print at up to 38ppm with a print resolution of 1,200 x 1,200 dpi. It supports both Windows RT and Windows 8 and has a paper tray capacity of 550 pages.
Other notable features include a 3000-page toner (whose replacement is actually quite expensive) and a Dell Money Back Guarantee offer which gives the customers "a full refund if they experience a genuine technical fault during the 12 months following product purchase."
