Well, I guess that emans you won't be sending that Mac to me!
As for shopping, you might want to try
SmallDog, they won't have the cheapest prices, but I'll garuantee they will know what they are talking about. If you "register" you can but new machines, otherwise, you have to visit the store in person. Of course, they also have refurbished stuff along with standard new machine warranties (Apple Care).
One thing to watch out for is some of these 'warehouses/malls' have a physical operation in various states. If you live in one of those states, they will charge you state taxes. Of course, Congress is working on a plan to force that on all of us in the future!
