I'm selling only one product and, ideally, when clicking the "buy now" button, the costumer will be redirected to PayPal. But, at least I would like the user to be redirected to checkout, not to cart, and from there to checkout, and from there to PayPal. Some customers may find that there are too many steps, for just one product. I've tried to put the code from checkout page on cart page, but it's not working. Is there a way to skip at least the cart page?
