$5 should be enough to negate the fee or provide a small profit (depending on which card you purchase)
All you need to do to redeem the offer is purchase any Westfield Gift Card from the concierge desk at Westfield Bondi Junction, Westfield Chatswood, Westfield Sydney, Westfield Kotara, Westfield Parramatta or Westfield Miranda and download the WhatsMine app from the App Store or Google Play.
This offer is available at selected Westfield centres from Wednesday 5 June 2019 until Thursday 20 June.
Minimum amount seems to be $10 (at least that's what the online portal allows).
$10 + $2.95 fee = $12.95, for total worth of $15 gift card to use
12.95/15 = ~0.863, so ~13.67% discount.
Discount percentage diminishes quickly as amount goes up, very small amount of discount in terms of actual value, but at least not bad for those who are around and have the ~10mins to spend. Or good for those thinking of getting the gift card as a present as it cancels card cost.
