I have integrated paypal with my site. My customer complaints that when they want to pay via credit card, paypal forces to register them and create a paypal account. Ho to get rid of this, as I do not want to loose my customer due to this complexity.
Well you can create button step by step from devellopers section and then just get one url by switching to e-mail from website and add parameter &landing_page=Billing. I did it this way but actually works only for some countries, like USA or UK.
