You can get every lego part EVER MADE at this awesome site:
It is friggin cool! You can get every set, part, ANYTHING that is affiliated with Lego; even some custom parts... I'm gettin loads of minifig bits an bobs from there and I'll have another moc up with all of my awesome guys in this castle I made soon!
The only problem is that is a site, but not a shop in itself. It has different shops on it, but they are all separate, and so you will have to pay a tonne on shipping if you just go about buying whatever from every shop you see...
They are all set up by different individuals, and so come from everywhere. It's like ebay, only you don't bid on them, which is cool cause you can just buy whatever you want for a fixed price, BUT you will need to get as many parts from one shop as possible, or it could be VERY expensive for you...
