How to get Computer Hardware?!

If I wanna get my Parts by the cheapest way.. I live in KSA, so what's the best thing I can do.. buy from newegg and ship via myus? whats your suggestion.. ?

Newegg would be my first suggestion, Amazon is usually pretty cheap too.

Why dont you buy parts from within Saudi Arabia? isnt there like no sales tax there?

that shipping would be pretty steep wouldnt it?
