Free standard delivery for purchases over $100. Or free click and collect.
Pretty decent price if you signed up for the 'spend $100 get $20' Amex cashback deal, expiring 26 May (https://www.ozbargain.com.au/node/377360). [Edit: just realised that the AmEx cashback also excludes Miele, but I'm not sure how they know what you've purchased. Removed from title just in case.]
Unfortunately no Cashrewards or Cashback with this one since Miele products are specifically excluded.
Always a sucker for a good vacuum pun…
