hi all, we had trouble distributing promo codes for IAPs and iTunes purchases because some people would take more than one, and users have to try 10 different codes before finding one that works. we built a free service for managing digital coupons: it limits people from taking more than one and shows how many are unclaimed at any time. http://www.tekiki.com/app-deals/promo-codes/create it's free. feel free to use. would love feedback. thanks!
