Cheapest way to get RE license in PA?

[Chris Hanratty]

I live in South Jersey just over the bridges from Philadelphia and that's where I grew up so I want to start out getting my license in PA and work Philly some to get my feet wet then adding a Nj license and work both sides of the river. I want to start slow doing it part time to supplement my income, money is tight. So where/how is the cheapest way to get my Pa license?
