How to add fees on some payment methods?

Hello,

I would like to know if there is any way to add fees on some payment methods ?
when i use for example moneybookers there is 2% should be payed so i want the customers who 'll use moneybookers to pay this 2% for example and if possibly to add alert popup msg to tell them what they paying.
for example when they choose moneybookers a popup msg come and tell them [ using moneybookers cost you 2% of the total price ]

I hope some one can help me with this so my customers know what they 'll pay and know that the price is not from me and it's cause the payment method.

That would require some custom coding that's probably beyond the scope of a forum reply. Many here, including me, would suggest that you not try to recover payment processor's fees from each order, but increase your prices overall a little to cover what is really just a business expense.

Thank you for your replay. I see that what you say is the only way i know tell now, But when you get another sites that sell your products with same price [ but they cost shipping and fees on the payment so they don't loss money ] so you need to put your fees in hide place :) or customers 'll go to the others and pay them in the next steps :( I hope if there is any solution. Also what is zencart 5 ??? i see there is part in the forum for it but i don't know where to get it or what is different between 3 and 5 ??
