Hi
I need some way to let my customers buy and pay directly at the product without "putting" it in the cart. I want my customers to buy only one product at a time. And I really don't need the shipping method selection either.. When the customer sees the product he or she shall click on a "buy" button (not an "add to cart" button) and be redirected directly to the payment/checkout page.. And if they leave the page without paying, I don't want the product to stay "unpayed" waiting for them to pay.. If they leave the page everything shall be restored and normal again.
My question is: How do I change the action method from registrating the product in the cart, to make it possible to buy directly from the products page.?
