PriceMarx strives to give you the most accurate price estimate possible. Most of the similar services have a hard time separating things like "smart phone" from "screen protector for smart phone" when you search for "smart phone". The result is a price estimate obtained by averaging the price of $500 and $5 items. Our proprietary technology uses collective intelligence of our users to learn how to distinguish such things to provide you with accurate, meaningful and useful price valuations.
In addition to the fair price estimate the app is a great comparison shopping tool providing you with links to merchants' listings at merchants' sites.
You can also access our service with a Web browser. Please visit us at http://www.pricemarx.com.
