Which Comparison Shopping Site Is Best?

Tracking down the best prices for everything you buy can save some serious cash when economic times are tough.

That’s where price comparison search engines come in. Just type in the item you're looking for and a list of offerings from online retailers pops up, with the best deals clearly highlighted. "Even if you're not buying online, it's an important way to raise price consciousness," says Edgar Dworsky, founder of ConsumerWorld.org, a consumer advocate. "You'll have some perspective on whether the prices you see [in stores] are good ones."

Finding that right price-comparison search engine, on the other hand, is a tougher order. Each site uses its own formula to determine how, when and from where it gathers prices. Some focus on specific categories, like electronics or books, while others only feature listings from partner retailers. The bottom line: Some comparison shopping sites are better at digging up great deals than others.

We put nine major price comparison search engines to the test, hunting down the best prices on eight products: For children's toys, we searched for Hasbro's (HAS) U-Dance videogame and the Lego Agents Mobile Command Center (both from Toy Wishes magazine's Hot Holiday Dozen list). Then we looked for a purple 8GB iPod nano and 7 for All Mankind "Ginger" jeans. In books, we searched “Hot, Flat & Crowded” by Thomas Friedman and “Nights in Rodanthe” by Nicholas Sparks (both listed on The New York Times Best-Seller Lists). And, among electronics and appliances, we sought a Cuisinart SmartPower Premier 600-watt blender and a 58-inch Panasonic (PC) Viera TH-58PZ800U (winner of electronics review site CNET's Editors’ Choice Award).

Returning low prices was important, but accurate results were just as vital -- receiving a bunch of listings for purple iPod nano cases, for example, when we wanted the actual device. We also took note of sparse listings where just one or two stores were listed for popular products (like the Legos) or widely-distributed items (the books).

PriceGrabber.com was the clear winner, with results repeatedly among the cheapest and most accurate. Its detailed listings -- factoring in everything from sales tax and shipping to an item's condition and store availability -- made for easy, at-a-glance assessment. Yahoo (YHOO) Shopping came in a close second, with great prices and a buyer protection program to protect users in the event of merchant fraud.

Wondering which other sites are worth bookmarking and which are not? Here's how the competitors performed, from best to worst:

Comparing the Comparison-Shopping Sites
SiteFeatures We LikePerformance
PriceGrabber.com Earn $5 rebates by adding reviews for select products. Although it initially puts featured merchants up top, "Your Best Price" is clearly labeled.Excellent. Its prices were among the best in every search, coming in cheapest in three categories and a close second in two others.
Yahoo! ShoppingLook for the buyer protection icon below partner merchant listings -- it means your purchase is protected against fraud.Great. Pulling from the widest range of retailers, it found the best prices in three categories and was competitive on the rest.
Shopping.com  (partner site DealTime.com offers identical results)Broadens shoppers' options by including eBay listings. Extensive reviews help users determine a product's quality.Good. It found the best prices in three categories. One hiccup: It offered us a Mintcraft Dancing Sprinkler when we searched for U-Dance.
NexTag.comPrice history tracks the item's price over time, as well as the number of retailers carrying it.Good. This competitive engine's results were near the front of the pack in four of the eight searches.
Shopzilla.com (partner site BizRate.com offers identical results)Tweak results using the price range feature to weed out both too-expensive and too-cheap (say, used or refurbished) versions.OK. It turned up the best prices in two categories. But its results weren't always easy to negotiate – almost half of its "Nights in Rodanthe" results were older, out-of-stock versions.
StreetPrices.comDidn't find the right price? Use links to find relevant listings on Craigslist and eBay. Or set up price alerts for notification of price drops.OK. Its prices were among the best, but it failed to find the Legos, jeans or blender. (Spokeswoman Autumn Looijen says StreetPrices recently branched out from its focus on electronics and is working out the bugs.)
Pronto.comSet price minimums and maximums to focus your search. Find the best deal by sorting among lowest base and total prices, as well as the highest store ratings by reviewers.Hit or miss. It turned up some good prices, but found zilch on the videogame and the jeans.
Google ProductsRefine your searches to pull up items by certain criteria, say a product within a set price range, from a certain store or bearing a good seller rating.Hit or miss. It picked up a wider variety of stores than other engines, but sparsely detailed listings -- no sales tax or shipping noted -- made it impossible to gauge total price. (Google says the tool's aim is simply to find products and point consumers to the stores that sell them.)
PriceRunner.comDate verifications keep you apprised of the latest store prices and availability.Skip it. It only found the iPod and the blender. "Pricerunner.com is competitive search engine," insists spokesman John Ardis. "It's in the top 25, and it didn't get there by mistake." He declined to comment specifically on the problems we encountered.

I always use price comparison service before buying any product. But most of the comparison shopping websites show prices from few sponsored merchants. But recently I looked at the website www.priceexplorer.com. This website provides unbiased price comparison service. I liked this website very much and I always do a price comparison on this website.

I have using Shopzilla for a little while to compare a general items. I prefer Onewayshopping.com and Price Grabber to research the lowest prices.

I have to say this about some of your statements. It is not the fault of the shopping engine for providing out of date products, prices or information. Each participating vendor provides a file with the product information for their particular store. The shopping engine only displays qualifying results, with one exception; Shopping.com does seem to be a little creative with the results they display and whenever we update our inventory and prices through out the day, Shopping.com lags anywhere form 6 to 12 hours to update our listings. I know this because I perform these functions on the shopping sites for my company. Also, to the user who made the comment about the value of customer service being important in the ratings; very true however, for the most part if the shop/store is on the ball, 95% of the time you should not need customer services. That is one way I look at ratings - whenever someone writes about the purchase they made online and the great customer service - it makes me ...(Read more of this comment)

well, low price is attractive, but service is vital too. In spite of some defect in system improvement, Amazon.com is becoming more and more prominent, which has now combined comparison function for price and shipping into its specific product detail pages, and don't foget its famed shopping guarantee. As to some cheap and good purchases, www.palrate.com, overstock.com are my favorite choices, go and try your luck.

Comparison Shopping: A Safe Option For Your Wallet
Often when you are in need of a product or service, you think of one store where you do most of your shopping, drive there, buy the product and take it home. You may not consider shopping at other area stores or online. This means that the only comparison shopping you are doing is from the varying brands or options that the store has in stock. This may be murder on your wallet!
Fortunately, the internet has opened up a variety of new options that help assist you in comparison shopping for that desired object that you need. You are now able to get on many websites, pull up the item you want, see what that store sells the product for and decide which one you would like to buy. Most sites will offer you the option of purchasing the item then to secure the selling price, often with a low or non-existent shipping fee. Some even mail the item directly to your house, without you ever having to leave the comfort of your home.(comparis...(Read more of this comment)
