I used to order from newegg because of the cheap/free 2 day fedex shipping and the lower than average prices. Now the prices are still a little below average (but not as much) and they use UPS 3 day (yuck). However, I still order almost exclusively from t3h egg because of their selection and I've never had a problem when ordering from them. If there is another site out there with the prices and selection of newegg, they will get my (considerable, more than I want to know) business.
For example, I just ordered:
GA-X38-DS4 for $199.99
Intel Q6600 for $260
G.SKILL 4GB(2 x 2GB)DDR2 1000 for $114.99
At zipzoomfly, the q6600 is $278, they dont even have the motherboard and similar ram is $130 for 2gb (I got 4gb for $115). That said, ClubIT looks nice (their UI sucks though), they have the mobo I bought for a wohle $1 less than newegg.
EDIT: on second examination, ClubIT is pretty nice... I might have to check them out the next time I place an order.
