Recently I saw a brief tutorial on a social website that really captured my attention. It was posted by an ebay reseller who scanned a manufacturers barcode on a packaged item. He immediately got numbers on how many of that item was curreently listed, sold items, prices, average listing time, and more. Does this feature really exist? If so, what is it called and how can I learn more? As Im writing this, I can picture all who read it laughing and calling me a naive fool. Let me down easy please.....
