Online services like WishRadar, RetailMeNot and DealLocker can help you find bargains -- and one site will even pay you for searching.
Buy a refurbished laptop or other piece of hardware: In the market for a new laptop? Maybe one of those spiffy Dell XPS M1530 systems tricked out for entertainment? They start at around $949, but if you're willing to go the refurbished route, you can pick one up for as little as $729. That's the price I found in Dell's Outlet Store (shown below), which is home to all of Dell's desktop and laptop refurbs.
Clip some online coupons: Ever get to the checkout page at an online store and wish you had a juicy discount code? Why not spend a few minutes searching for one? Just pop open a new browser tab and search for the name of the store and the words "coupon code" (or "discount code" or "promotion code"). Or head straight to a code-collecting site like DealLocker or RetailMeNot and look for the latest offers for your store. You may come up empty, but you could also land a code that saves you 10 percent or nets you free shipping. It works about half the time for me, making the search well-worth the effort. Estimated savings: $50 per year based on my shopping habits.
