Paypal is a big online payment service. Unfortunately.
When you compare its fees with other services you see that these are considerably cheaper.
(Moneybookers, Paypay...)
Further I experience paypal as troublemakers. Other services are much easier to use for me and Paypal may even be inside illegal MC.
I can easily forgo on paypal but the point is that online shops often offer paypal as the only payment possibility. This should change.
