Well if you want to really pinch pennies do what I did.
Buy 4 Amazon gift cards on ebay for $570 each, with each being worth only $500 (theres a catch).
Sign up for microsofts live cashback program and you get anywhere from 15-30% cashback for each purchase for up to $200 dollars. I bought 3 when it was at 30% and another when it was at 25% (long story). Anyways, now I'm due back $651 dollars from microsoft. From what I've read over at fatwallet, everyone is getting paid unless you try to do some shady things like buy and resell the same gift card. Some sellers are losing cashback on purchases they made. To stay on the safe side, the consensus is only buy don't sell.
The only real catch is that you need to put the money upfront and you have to wait 2 months to get your money back. I paid $2280 for the gift cards and after microsoft pays me I will have paid $1629 for $2000 dollars in amazon gift cards.
Currently on Amazon the Macbook pro is $1965-$100=$1865 rebate (rebate takes 2-3 months to recieve so more waiting).
So in the end, you end up paying just under $1500 bucks for the new Macbook Pro. Not sure where you are but here in California you don't have to pay taxes for goods bought from Amazon.
As far as I know thats the best deal you can get, but you need to have extra money to cover the cost till you get the laptop. I felt like I was jumping through hoops but mid-December I'll get a nice fat paycheck from Microsoft. Thankyou Microsoft.
Oh I forgot to say, right now cashback is at 25%, from what I've read, it'll go down to 20% and then to 15% and then back up to 30%.
