i always buy from JEGS or SUMMIT, then you dont have anything at all to worry about, there prices are always competitive, and if you find something 3 or 4 dollars cheaper, its usually not worth the head ache, or google the company , call them before makiing a purhase , to make sure there legit and someone is really going to answer the phone as a business on the other end.. again, i recommend JEG's or SUMMIT RACING for any parts or at least make sure who your buying from is well know company.. just my .02 cents.
