Berkshire Record Outlet, or "BROINC," is a great source for SACDs at bargain prices. (They also have some blu-rays and many CDs.) In the past, I've received a few discs that were "cutouts" (still in shrinkwrap but with a marking or slash on the spine), but my most recent order was completely fresh.
