mypreorder integrates seamlessly with PayPal Express Checkout (where customers pay via PayPal) and PayPal Website Payments Pro (where customers pay by credit or debit card without leaving the site).

To use either or both of these (giving customers the option of both is good), sign up for a PayPal Business Account and then follow this guide for accessing your API credentials.

At this time we are no longer able to procure better-than-advertised PayPal fees for merchants with under $1M turnover (online) per year.

It is however possible to offer customers both PayPal Express Checkout and then direct card entry on-site using another payment gateway, such as Pin Payments, which has lower fees.
