I would like to have an intermediate page after a Buy Now button is clicked where the customer can add a promo code that I can generate.
A good example is here:
[url removed, login to view]
You will see where the customer is brought to the "Enter promo code" page before reaching the Paypal server. My store has only a few items but no color, size, etc.. like the example above, just click and buy item. I will give you the url in the pmb.
I need to be able to have different levels of discounts (percentages) and need to be able to generate the codes easily as well.
