ResQ credits can be used to buy food from ResQ.
You can purchase ResQ credits from the ResQ credits section in the app menu. You can purchase credits with a credit card, PayPal and other country specific payment methods. You can also earn ResQ credits if you get your friends to use ResQ or have received a ResQ discount code.
If you wish to purchase food using ResQ credits instead of a card you've added to the service, you can switch your preferred payment method to ResQ credits before making the purchase.
ResQ credits are valid for one year from the previous purchase. For example, when you purchase ResQ offers or credits, the time is reset.
