I've been using ejunkie for a couple of weeks now and am really impressed with it.
What I want to do now is set up a parser with my Aweber account. However, for both my products I already have the stamping feature enabled.
So when I want to set up my parser I have to enter a URL into the 'Payment Variable Info URL'. However, this is already populated with the stamping URL.
How can I have both stamping and parser set up simultaneously for my products.
