So we have all had products (especially Games & DVD's) which we are not sure if the sales rank is being driven by the Used market or the New market.
We can can get them for a great price but are just a little scared to pull the trigger! Well to combat that and eliminate any guess work I use a spreadsheet along with a screen capture programme.
This allows me to monitor the products and determine whether the New or Used market is controlling the sales ranks.
Checkout the video below where I will show exactly how I do it.
