I get my x-pound bags of Lego on eBay. I do occasionally get some clone brand stuff in there, but I always go through and remove them.
The only downside to this is that I have to clean the parts most of the time. The first bag I got was half-full of dirt.
Send your armies. There's no man or machine who can stop me, and you'll soon see.
I come for vengeance for the first Son of Light and I'm ready, and I'm willing, and I'm prepared to fight.
