Brick and mortar to mean a store which has a physical building, I accept readily, but I'm not ready to accept B&M for any physical entity whatsoever. In addition, you could order a "B&M OED" from a non-B&M store (e.g. amazon.com) - isn't that like ordering a leatherbound OED from a vegetarian store. (^_^)
