The first big move, in my opinion, that PayPal made was when they made it possible for non-PayPal members to use a PayPal merchant account on sites.
When I visit new businesses thinking about adding a merchant account and selling online I usually tell them that if they are not selling $2000 a month then it would be best to go with a third party merchant account instead of a merchant account of their own. One, because of the cost savings, and two I would recommend it for businesses just starting out.
