Least expensive way to get a RE license?

[N/A N/A]

Hello,
I was interested in getting my Florida RE license. I've talked to some local offices, they quoted me around 500.00 for the course. My local community college charges around 250.00, but they don't offer night classes and there's an online site that is 300.00, but Im not sure if it's accredited.
If I go to amazon.com, buy the books, take the practice tests and score well, is there a place where I can go to take the test and pass?
I've heard there is some online courses that are 88.00, but I googled it and couldn't find anything.
Thanks in advance for your help
