I used ZZF alot back when it was GoogleGear (got threatened by THE google for the name) anywyas, I liek them theyre decently low prices, BUT I've found that the reason that they have cheaper shipping is because they are a few bux more expensive..
I just go to all of them to find the best price (incl SH)
you can also use meta search engines like pricewatch or pricegrabber.
and of course theres EBAY.. (I HOPE you never use it for comptuer parts )
I just got done ordering $350 worth of parts off of zzf. I think Newegg and ZZF are about even most of the time. Like half of the items are cheaper to get at ZZF and the other half are cheaper at Newegg. But mainly it's just by a few dollars.
Yes, thats true; ZZF is for the more experienced people who know exactly what they're looking for, specs and all. Newegg is a lot friendlier to the beginner and gives more specs than you'll ever need -- In a very user-friendly fashion.
