Unfortunately, I am only able to receive payments using PayPal, however with this in mind I want to make the best out of it.
Using PayPal's "Buy now Button", the normal way to proceed a payment would be:
1. A - by PayPal predefined - form on my site with a submit button.
2. After submitting, my site is replaced with the PayPal payment site.
3. After the payment process is finished succesfully the PayPal site is replaced with my site.
Is it possible to open a new window with the PayPal site after submitting there predefined form.
