favorite sites to order?

I want quality parts but at wholesale (dreaming I know), or below retail prices. Since I started building computers years ago, and discovered places to build computers from parts, that retail for 3 grand at only 800-900 bucks, I've become so anti-retail. I've noticed that a lot of people are anti-ebay. But I've found some great stuff on eBay, and cheap. Granted I would never buy anything like coilovers on eBay ($40 bucks is too cheap for even me to not think something is fishy about the auction), but I have bought altezza lights, and other stuff off eBay, mostly cosmetical stuff.

Body kits seem to be cheap on eBay, but it makes me question the quality of the product. Why are online sites offering kits for $800-1500 while eBay has them as cheap as $250.

I know you get what you pay for, but I've also know there is always companies out there that dont mark way up, and still make profit. Any directions to point me in? :)

Good luck :) I'd try the junkyard, as its the only place you will get a part for a reasonable price and not get raped on shipping...

www.rockauto.com has some pretty good prices

www.gmpartsdirect.com

AJUSA.com on most parts and mostly free shipping.
