I am responsible for purchasing new computer hardware and related electronics for the Alumnae Association. I read a lot of reviews and compare prices. A site that makes my job easier is PriceGrabber.com. They provide one of the best product filters I have seen on any web site which allows me to easily narrow my choices and compare apples to apples. Amazon is finally offering a similar filter option.
When you select a particular item, it lists all of the vendors that sell it with direct links to the vendor product pages and shows the selling price, along with taxes and shipping (just enter your zip code) and the real total costs. Some vendors advertise a low price only to charge more for shipping. There are seller ratings so you can see the experiences of other customers.
Pricegrabber features more than computers and electronics now. Categories include travel, home& garden, kitchen equipment, health & beauty, movies, video games and more. Before you spend your money, shop and compare because sometimes prices can vary significantly. If not the prices then the shipping, service and support.
