Hi 

We have an e-invitation website for which we would like to install your plug in 

There are couple of questions I have 

Genrally there are two sides of front and back of the invitation  card 

But our designs include 3 pages , so is it possible to add product with 3 pages and customise them all .

Secondly we want our customers to pay for the downloading the design once customize , can it be done ?
