In my ongoing attempt to help you spend your money on more and more Lego, I bring you a few more online commerce sites. :-)
Apparently there is a site called Brick Owl that is similar to Bricklink. There's also a minor controversy surrounding the new owners of Bricklink. The New Elementary says it so much better than me so I'll let him explain. And then there's this site called Bricksy.
There's also a new site based around trading minifigs. I know we're not big into minifigs as a community, but this could help you get rid of some that are taking up space for others that may have usable parts you need.
