We help lots of merchants sell on-line. One big problem is the fees charged by the banks for processing credit card transactions. Well not today but in the next few years the EU is going to sort this out and stop the banks milking consumers much the same way Telecom companies did with roaming charges.
There is talk of limiting the fee to .2 or .3 % of transaction. Currently it can be as high as 1.5% . You can check this story out on the rte web site at http://www.rte.ie/news/business/2013/0717/463007-europe-card-fees/ .
Hopefully it will put some pressure on PayPal to do the same and lower it’s fees.
