Hi there, 
just still playin round with my coupon system, and noticed there needs to be a monthly, quaterly and yearly option for the coupons if they are reccurring, like, if the user gets a coupon that is reccurring the price needs to get adjusted accordingly. for example 
$20/m discount reccuring 
if a user pays for a year, it still shows up as $20 of a discount instead of 240 
  
but on that note, keep up the good work
