There are two general types of codes in ResQ:
discount codes – when you get e.g. a 50 % discount on the offer's price – and
credit codes – that add ResQ credits to your account, and you can use them to pay for orders.
All types of codes can be activated by inserting the code in the "ResQ codes" section found in the app settings. Codes cannot be added when making a purchase or after the purchase has been made, so remember to add them before you place your order.
Once you have added a discount code to your account, it will be used automatically for your next purchase. Adding a credit code will add credits to your ResQ account, and credits can be chosen as a payment method when making a purchase. You can read this article for more information on how ResQ credits work!
Please notice that some of the ResQ codes have an expiration date. You can see the expiration date and the description of the discount under the inserted code.
