Was looking for Wish Gift Cards and the highest discount was 3%.
Macquarie members can enjoy a 4% discount.
It is free to join and no yearly fees.
One downside however is that you can only pay with your Macquarie balance and cannot add alternative methods of payment.
It's not a deal, thats their normal discount and has been for ages. It is listed in the Discounted eGift Card Page and isn't even the best discount.
