Every other model of Dyson's Big Ball got the love recently but the multifloor missed out, and I've been waiting for it to go on sale - And as luck would have it, not only did it drop from $699 to $492 at the Good Guys (a great deal by itself), but they're doing an eBay sale as well. Basically a 40% off deal on Dyson, which it just nuts.
Double dipping isn't enough for me though, and QANTAS just sent me an email to shop via their mall (https://onlinemall.qantaspoints.com/ref/pgmerchModal/mid1565…) and get 1 point per dollar spent (only about $2 worth but I'll take it). I'm sure you can use cashrewards, AMEX and a few other tricks to get even more value out of this deal.
For those wondering why this model is so special, it's the ONLY Dyson model to come with a proper multifloor head. So if you have hard floors with rugs, this is the Dyson you want.
