Hi all. I'm setting up a store with custom paintings. It works like this:
1. customer uploads a picture of him
2. I create a painting from the picture
3. Painting is printed on canvas and sent to the customer.
How can I add a digital download as an add on product?
For example, when customer is about to check out, ask him if he wants a digital download of his painting for an extra x amount of $?
