Nice discount at MacMall, but from what I've heard and read, ordering from them is a lot like playing technology Russian Roulette.
Many, many customers have complained that they have no recourse if the wrong item ships, or if the receive a DOA piece of equipment.
From my own personal experience, their customer service people are extremely curt, verging on downright rude.
I'd be looking for the same kind of discount at another retailer.
