Shooters Warehouse is pretty crappy. Overpriced and horrible selection (even prior to the crazed buying). Shooters Warehouse with the crap CS is still a billion times better than the POS staff at Sac Black Rifle though. They have no issue price gouging and being complete a holes at the same time. At least most other places are still nice to the customer while charging absurd prices.
As sactobill stated, MTG is a great shop. Their inventory is almost depleted, but great customer service and they are not price gouging.
