Dyson Pure Cool Me Air Purifier 70% off [YMMV] [IN STORE - Target] $104
I was in my local Target today and found one of Dyson's smaller air purifying fans that typically go for $349. So I grabbed them both. I took a look a Brick Seek and it looked like they are marked down at quite a few stores.
I've got a few of the larger Dyson fans and love them. I wouldn't pay $350 for these small ones, but they are WELL worth the $100 price tag imo.
