Am I getting ripped off by Pay Per Click??

[Just Kate]

I have this new website ( dkcrystaldesigns.com) and I have registered it with Yahoo & Google. I am getting lots of clicks from them but no sales. It is costing me a lot of money to register with them with pay per click. How can I get real traffic to my site without paying a lot of money. I am affraid my online store is going to go down them tubes and take all of my money with it if I don't find a short cut FAST!! Also, Has anyone heard of OrangeSoda.com??
