Powerful little tool Rated 5 out of 5 stars

Paid for the 3 month subscription on this and am happy to report that it is money well spent. This add-on is a huge time saver. What used to take hours can now be done with one or two clicks. With another click you can download the results into a spreadsheet. Do this multiple times at set intervals and you can estimate how much inventory is moving and who the big players are on any given listing. I already feel like I have a much clearer picture of the inventory levels and movements on a number of key listings. This is the vital data you need to make rational decisions on pricing--whether to compete aggressively for the Buy Box or simply wait for the competition to run out of stock.

This review is for a previous version of the add-on (1.4.0).
