I think it's similar to PayPal As far as I know,You can use Escrow if you want to accept large amount from someone..
PayPal is best, But they don't accept some countries. That is why Moneybookers and alertpay like plate-farms are in to use. Moneybookers is also great one. I am using them from 2 years. Just WOW. Thanks !
Moneybookers is a great payment processor. I've been using them for a couple years now and never had a problem.
Moneybookers.com is the payment portal you need to give a try. I am using it from quite long time. Thanks
