Receive 5% cashback on Airbnb gift cards when you buy them on the Cashrewards website or app. There’s a daily purchase limit of $1,000.
You can buy Airbnb gift cards for 5% off at any time just by opening a free Macquarie bank account but if you’re not interested in doing that then 5% cashback is the best alternative, especially if you want to pay with a credit card.
