Storefront Scheduler PRO is a Chrome extension that will track the contents of a competitor's Amazon storefront. This extension will allow you to create a custom “schedule” of how often you want a list of that seller's store contents emailed to you in a .csv file (to be opened in most spreadsheet applications). The extension will highlight which items were “new” or “replenished” since the last update, allowing you to create a fresh shopping list of potentially profitable items to sell in your own Amazon store. The data returned includes the ASIN, title, shortlink to product page and notification if it is new since the last scan. The updated version allows you to track multiple storefronts at the same time.

This extension will give you a real time look at what other sellers are sending in, enabling you to capitalize on trends and popular items you may have otherwise overlooked. You could take your list into Tactical Arbitrage or OAXray to help you source the profitable products.
