While not actually a shopping cart, if you only have a few products and your customers are willing to pay only by PayPal, it’s relatively quick and easy to set up a PayPal account. It is now possible to accept credit cards with PayPal Pro which adds merchant services (credit card processing) to your account.
So what is about you want to know? You were right when you said that paypal now adds merchant services. I can't seem to get what you want to achieve in your post.
Yes that is true, however, their fees are a bit higher than traditional credit card processing. It you have a high average ticket then this could be a lot of money left on the table because each one of those bank transactions will cost a lot and it could be a significant savings to use traditional credit card processing. Not that I am the authority on any of this, it's just my opinion. Anyway, this is my first post. Hi everyone. Ciao'
