My experience with them for 3 bikes is that they are generally about 45% less than LBS pricing for relative value - more on a few special situations. Each bike was received in a week or less.

Issues:
-I preferred a shorter stem on the first bike. They offered to exchange it, or sell me a new one for 50% of retail and no shipping. I took the latter deal.
-On the third bike, the fork was supposed to come with rack brazeons, but did not. Apparently they changed to a color matched fork that mated perfectly to the integrated headset, but did not have brazeons. They immediately sent out the old style fork (black with brazeons) with a UPS return label for my fork.

FWIW, I just ordered a fourth bike from BD for my fiancee.
