Hope you are doing good.
I am watching your Woocommerce coupons tutorial and have a problem. I am using WP optin wheel and one user can spin the wheel once in two weeks. This means that if the user wins, he will get a coupon he can use once. But what if he wins the same % coupon again? How can I validate this and how should I know that the user is not using the same coupon again and again? Because I am not placing an expiry date on coupons as the wheel will remain on my site unchanged.
