I been using sites to save money for over 10 years. These sites compile some of the best deals so you don't have to do all the leg work looking at ads. I am able to save a considerable amount each year. It allows me to save time and quickly scan through and create alerts on what is on sale.
These sites also have different forums hot deals, coupons, freebies and finance. They are a good source of information to help you save for an overall strategy.
I recommend two sites:
1. Fatwallet - http://www.fatwallet.com
2. Slickdeals.net - http://www.slickdeals.net
Some of the deals I was able to get include TV's, clothing, housewares, credit card offers, food discounts, computers, console systems, games, electronics, and hotels/travel.
