What are the options I have if I want to buy a new MacBook Pro (15" retina) in a physical store, with cash, preferable with discount? Of course there is Apple Store, and I see that Best Buy is also an option. But I see other places selling it for a good price, like BH and MacMall, but they don't seem to have physical stores? Is there any option? My reason is that I'm from outside US and I will be in Miami only for a day so I'd like to find a store with the mac in stock and purchase it there, in cash. Thanks.
