Have you noticed a drop in traffic don, or the numbers are about the same?
I did notice something regarding you payment options. At the moment the way you have it set out with the icons, you are displaying that anyone who wants to pay with a credit card should choose PayPal by listing all the card icons with the PayPal icon.
What you are doing is bleeding your Paymate option completely dry because you are directing credit card payers to PayPal, and not providing any payment options that Paymate offers.
I would suggest just using a PayPal icon, no cards included at all, then include the two card icons for beside the Paymate icon, and make a note to inform people that they do not need a Paymate account to use the option.
At the moment I would imagine most of your customers have never heard of it, all they see if they can pay by PayPal, or if they want to choose a card, they can pay by PayPal.
Lessen the PayPal promotion, pump up the Paymate option, and that includes positioning it on top, not underneath PayPal, that sends a signal that it is your number two option.
