This year's Cyber Monday is expected to be the biggest online shopping day of the year for the third year in a row: According to research firm comScore, Americans are expected to spend $1.5 billion, up from $1.25 billion last year on Cyber Monday, as retailers ramp up deals to get shoppers to click on their websites.

Brad from Brad's Deals called in to the show to let us know that he and his team are covering "Cyber Monday" like a newspaper covers the news.  His 48 member staff spends hours scouring online deals so you don't have to!  

Brad's advice: DO NOT PAY FOR SHIPPING!  He told us too many retailers are offering free shipping for us to bother with sites that don't.  You should consider shipping costs into the price.  Some online retailers will pull the ole' bait and switch, meaning they'll make up for discounts by charging you an arm and a leg for shipping and "handling".  (Frankly I have no interest in paying someone to fondle my purchases before they ship them.)

You should also check out Shop.org's official Cyber Monday site.

If you're in the market for electronics, then stop by Decide.com for advice. The site uses pricing history and statistical analysis to estimate whether a given product is at a good price or if your patience will be rewarded. It claims 77 percent prediction accuracy.
