How to automatically provide one time coupon codes
Some companies are moving from the practice of static coupons which are active for a certain period of time to 1 time coupon codes, which can be used once only. A list of coupons will be provided by advertisers and we have to serve a new coupon every time.
How do we manage such a situation? Is there a plugin which can be used to perform such an activity?
Any help is appreciated.
