Smart online shoppers know that there can be a wide divergence in price between the same products from one e-tailer to the next, so in order to obtain the best deal you need to know where the bargains are. To that end, we here at eBizMBA have provide you with the Top 20 Most Popular Sites for Bargain Hunters ranked by a combination of Inbound Links, Google Page Rank, Alexa Rank, and U.S. traffic data from Compete and Quantcast. For entries where a wide range exists between the two data sets the highest numbers were used for ranking purposes. Although no traffic metrics are completely accurate we do believe the data below to be useful for gauging relative audience size.[Sites like Amazon, eBay, and Craigslist have been excluded, because while bargains can be found there, they are not primarily comparison shopping tools.
