Been looking around for a few months for a deal on one of these, seem to be few and far between on the respected brands (Bionaire & Premiair). The next best I could find was a Bionaire one on Argos at 25% a few weeks ago but they must have gone quick.
Best price for this including delivery has always been Amazon (£65), add on the replacement filter (£15) and you're looking at a saving of £25 of normal (not RRP) price. Might not be a killer deal but its been a nightmare trying to find a deal at all.
