Coupons are gift codes that you can give to your users.
To each coupon you can associate a number of coins to give to your user, how many time the same coupon can be used and when it expires.
You can generate a new coupon from the admin panel in the section “Coupons”.
If you want you can generate multiple coupons at the same time setting a number in the field “amount of coupons to generate”.
After you click on submit the coupon codes will be generated and saved in the website. I suggest to set a description so that you can find them easily.
You can give coupon codes to the users for example in a giveaway or in an event. Users can redeem the coupon from the item shop.
After they write the coupon code and click on submit, they will received the amount of coins that you have configured.
A coupon cannot no longer used after it is expire or after it reaches the maximum number of time it can be redeem that you set before.
