SourceMogul has been a huge help to me in sourcing products online. It saves a ton of time poring over websites and analyzing products. The interface is extremely easy to use and shows all the information you need to make an informed buying decision. I especially like being able to search by Amazon category. They are continually improving the software and adding websites. Whenever I have a question it is easy to get help. Plus, they often ask how they can improve the software and take the time to listen to suggestions.
