I have been there twice and I didn't find it to be that great for re-selling
parts due to the quality. This may vary from location, but the bricks in the
bins were quite scuffed and probably great for kids to add to their collection
of play bricks but not good enough quality for listing on BrickLink. The minifigures
they sell are on the pricey side for Used minifigures. I bought a bucket of bricks
that I thought were in pretty good condition but once I got them home in better
lighting I ended up donating about 75% of them. I went back a second time a few
months later to see if it was just a bad batch I was picking from and they were
the same. It could be great if you are needing specific parts and quality isn't
as important to you. Anyway, this was my experience. Others may have a different
view, and it may depend on the location ownership.
