Product Features

The premium version looks like a great product for me, but two questions:
1. Instead of forcing a successful customer to go back to his account on my website to get his coupon code to share with his friends, I would like the system to automatically send my customer an email with his coupon codes to share.
2. You probably have a workaround for the following issue: when my customer sends his coupon code to a friend, who then the friend buys something from my website, an email goes out to the referrer with his reward coupon code to use on my website. Instead of the referrer getting a discount coupon for my website, I would prefer to give him a paypal or amazon card. Do you have an idea of how I could do this? I was thinking of maybe “selling” him the Amazon gift card through my website when he puts his reward coupon code into the cart, but maybe there is an easier answer? Thanks, rob
