Where Can I Get the Keyword Elite Discount?

Based on my research, it looks like Keyword Elite is the best keyword tool for keyword research and niche marketing. However, it carries a hefty price tag 6. I'm new to Internet Marketing with limited cash, and 6 is a lot of money right now. I've seen some posts around forums and some Google searches showing a Keyword Elite discount for .50. Are these sites legit? Can someone tell me of a reliable website where I can get the Keyword Elite discount for .50?
