Yes that's right. I love DownLoad Guard! All I did was add a coupon form to my product - with the help of DLGuard - and then I Give my affiliates a $5.00 off coupon code. I put it on my affiliate page . Then they can use it, if they so choose, in their promotions to increase their conversions. It works like a charm.
Not only has it helped to increase conversions - but it has also been useful in increasing sign ups to my list.
