The trade-in was a major factor in getting a great deal for me.I was given a price for my old G5 $980,(that included my old monitor), and the no-hassle transaction is a plus compared to dealing with an unknown party.Second, no tax, so from the tax savings, retail price savings, savings from add-ons like more Ram and a larger HD, and they are an authorized Apple retailer, it was a no-brainer for me
