Long time lurker, first time poster.
WIfe have been hankering for a Dyson fan for a while, figured the Amex cashback offer was a pretty good time to get one from Harvey Norman. To our surprise, the price dropped from $525 to $399 yesterday. Price is further reduced to $266 if you have 2 Amex cards to take advantage of the offer.
We topped up the payment on the second Amex to $300 with a Vpay card.
Hope this is of use to someone!
No idea why anyone wants to dump 400 bucks on a fan, even at 266 it's only relatively cheap, no where near cheap in iteself
