As I stated on a previous thread, I am still learning how to use a simple PayPal “add to cart” button and now I have some questions about shipping:
Let’s say my client wants to charge $8 shipping for a shampoo bottle, but if the visitor wants to buy an additional one (same product), he will charge him only $5 per extra unit. How do I set up this in PayPal 'add to cart' button? Where do I go for this?
Thank you for all your responses in advanced!
