No one says they carry them. AutoZone, Advance Auto and NAPA all say they don't carry and can't get Monroe 550012/550013.
Very annoying that an auto chain doesn't require all their stores to carry the same items.
PepBoys can get them at $69 each installed ($52 for the shock, $13 installation).
Now, I'm not a big fan of PepBoys (they dumped Antifreeze all over my opti when they replaced my waterpump) but $52 for installing all for isn't bad, especially since I don't have a driveway/garage I can install them.
So unless anyone else has a better idea, I think I'm going with Pepboys.
