Promo2.it is a URL shortener for sending out Promo codes. It not only lets you send Promo codes for your apps far more simply than giving directions or a long address, it lets you use your affiliate code too!
For the easiest way (which doesn't do any affiliate ID) simply use the address promo2.it/PromoCode and that's it.
To use your affiliate code, you must have setup your app with a shortcut on App2.it, then you can use the address promo2.it/AppShortcut/PromoCode and we'll do the rest. For example promo2.it/ftp/XXXXXXXX would send a promo code and use our "ftp" app shortcut (aka FTP On The Go) for the affiliate information.
