Pay-pal is our payment processor and we have been using them for over Eleven years now without issue.
You do NOT have to have a pay-pal account to pay for something using a Credit Card.
When transferred to the payment section you will find an option to pay using a credit card as a non pay-pal account customer. This varies in location from country to country but is there somewhere on the payment page.
Don’t you use Phone payments or other systems?
No, unfortunately we have found them to be exorbitant in their share, often taking 50% or MORE of the funds you would be paying in support. This to us is simply not sustainable.
