I am planning on creating a wesbite that will give out promo code for discounts for buyers to buying stuff with bitcoin.

 There will be 3 parties involved ; Me (the website) , Shop , Buyer

 Buyer will come to my website and get the promo code
 Buyer will use that promo code in the Shop
 Shop will do discount for the buyer
 Buyer buys the product or service or whatever with discount thanks to promo code
 Shop gives me a cut (big or small wouldn't mind)

 This is the idea.

 How does that sound?

 Also where can I find shops like these that would affiliate with me for promo codes so that I can give discount promo codes to people?
