BestBuy currently has a %20 off small appliances coupon out anyway, so thought I would give it a shot to get another 10% off there, which I was able to work. The trick is to have them take the10% off the sale price of $479 first, and then apply their 20% off.
$479.99 - 10% = $431.99 - 20% = $345.59 + tax.
I would think same deal would work on any Dyson really, so Cinetic animal & allergy = $403
Should be good through Saturday when Dyson's manufacturer sale ends.
The other thing I thought, is that this should be a UMRP product, is to get Kohl's to match the standard $479 and then use their 30%. (promo code: SPLURGE30 by the way). I like my BB points more than Kohls cash though anyway.
