Occasionally Seatfrog will offer a promotional discount code for money off a transaction. The discount code given can be limited to just one product unlike credit which can be used across all in app purchases. Discount codes will have a set number of uses and an expiry.
To use a discount code it needs to be entered at the time of the purchase or bid.
If you make a bid one day and later acquire a discount code this will not be counted. To use the discount code you will need to make a new bid/purchase and enter the code at the time.
To use the code. On the payment screen, opposite "Have a discount code?" select the " Add " option
You'll then be prompted to enter in your valid discount code.
Type or paste your code, then tap the "Add Discount Code" button.
You'll then move back to the payment screen where you'll see the discount has been added.
