I like tiger direct for big things, like tvs. But for all parts, I'm kind of a newegg snob. The only thing that I didnt like, was when I bought my most recent item, my motherboard, because i had just fried the old one. (overclocked it too much, Burned through the motherboard) but anyway, they had shipped it through ground fed ex. And i dont know if someone didnt get the memo that it was over night shipping, but a week and a half later I got it. I had called new egg and they apologized and sent me a free 500GB external HD. But to be honest... I have never heard of Microcenter...
