Don't buy from Apple Store or Best Buy. They both charge you a lot.
Why not just purchase from Amazon.com, they charge couple $100 less than what other stores would charge. Plus there's no online tax (yet). You just have to pay $3.99 shipping charge and thats it. And don't worry, amazon is trusted, you can also shop at newegg as well for better pricing. Online pricing on
macbook pros are more reasonable than shopping at stores. I purchased my
macbook (amazon), at $1600ish when at apple store it was worth $2000 and at best buy it was under $1900. You will get lots of discount from amazon so keep an eye on that.
