Best place for used mazda3 parts? (taillights. fog lights, etc)

I need a 2007 rear passenger tail light, and passenger side front fog light. Where is the best place to buy parts used/new and what kind of price should I expect to pay? Found the tail light used on ebay for $95, but seemed exepensive. Fog light was over $100 on Amazon new.

Advice?
 
I would look at some scrap yards. They should have what you are looking for and ive heard they are fairly cheap.
