Afterpay Day, the four-day bi-annual shopping event running from March 17 to 20 will offer in-store and online shoppers up to 70% off products from Dyson, as well as big savings from Kmart and Catch.com.au.

Dyson will deliver savings up to $250, or a gift with selected purchases on appliances including the Corrale straightener and Detect Slim Absolute Extra cordless vacuum. The price promotions give $250 off the Dyson V8 Absolute cordless vacuum and $150 off the Dyson V7 Motorhead Origin cordless vacuum.

Gift with purchase offers apply to the following while stocks last: Buy a Dyson V12 Detect Slim Absolute Extra or Outsize Absolute Extra cordless vacuum cleaner and receive a complimentary spare charger and battery kit valued at over $150. Purchase a Dyson Supersonic hair dryer in Copper/Nickel or Nickel/Fuschia and get a complimentary case valued at over $99. With the purchase of a Dyson Corrale straightener in Purple/Black or Iron/Fuschia, customers can choose two complimentary gifts valued up to $148.

To support people in flood affected areas, Afterpay is asking customers to add a $2 donation to their order to Thread Together, an organisation delivering clothes to those in need. And for the first time, customers can experience Dropshop, a one-stop-shop to find limited edition drops, exclusive collaborations and the latest releases.
