I've spent last days to compare different payments gateways solutions. And I've seen that if I want to integrate a payment service (such as paypal, or authorize.net) into my website I need to pay a monthly fee (and not only transaction costs).
Is this correct ?
For these reasons, I saw it is much more convenient for me to use Paypal Standard Payment Method and to only pay transaction fees.
Could you tell me if I'm missing something, or something is wrong ?
