I happen to enjoy comparison shopping. I am very comfortable going five pages deep in Google results trying to find the best prices. Some people are not so inclined. One popular way of shopping today is through the use of sites with shopping bots. These sites use bots to go out and scour the net for prices on an item. Then they compile all of the results and inclyde taxes and shipping. It makes comparison shopping a breeze. Popular shopping bot sites currently include shopzilla.com, bizrate.com, pricegrabber.com and shopping.com. What are your favorite comparison shopping sites?
