Currently I have two courses on monthly subscription. Although, it seems that once coupon code can be used limitless times amongst my users, if buyers want the coupon to apply to the first month of both courses, this is not possible despite me having set the membership plan to include ALL courses in the coupon section.
Currently, I need to give them TWO coupon codes.
Ideally, I'd want one coupon code that I can apply to each course as this is more efficient. So they buy Course 1, for 10% off the first month and get Course 2 for 10% the first month with the number of uses marked as two, so they can't use the coupon for other courses or the following months.
