I have been using pricewatch for many years.. back when it was just simple HTML with no frills hehe..
it is generally decent.. especially now that it shows shipping charges! It used to not show shipping charges..and some companies would have a real low price.. but then jack up the shipping 3x..
I have purchased from computer shows as well.. if you have any around you.. might be worth it to take a look... typically they carry both retail and OEM stuff.. most of the prices are close to pricewatch prices... you have to pay tax, but no shipping..
if you have some time.. take a look at
www.techbargains.com, they list deals on there.. they also list coupons..
some places like buy.com or staples.com carry computer equipment, primarily only retail.. but also have online coupons you can use... $20 off.. free shipping.. etc..
so check
www.pricewatch.com,
www.techbargains.com, and find the products you want.. weigh the costs (tax, shipping, product price). Shouldn't take too long to find out a few good deals..
I have purchased a lot of my stuff from
www.compuplus.com, no tax in CA and their prices are pretty good..
