Received an email from the card network thanking their customers and wishing a merry Christmas. In the email is a unique code used to get $20 off after spending $50 on all cards except the MasterCard or Eftpos cards.
The best card looks to be "The Gift Card" as it has eBay and JB on it or the card.gift gift card which can be used to exchange for any gift card on the site.
Eligibility looks to be you have to had exchanged a gift card previously to get the email.
No email for me
