Their repricing tool is excellent and at a great price. It has saved us the hassle of having to reprice our products manually and has won us the Buy Box on Amazon on the majority of our listings. It does not begin to reprice until you have set your minimum prices and repricing rules, which I think is great because if you have not had the time to do so, you can rest assured that you will not be losing money. The only downside is that it does not have better rules to price against merchant fulfilled sellers when there are no FBA sellers on listings (for example: If there are only FBM sellers on a listing, price a certain % over them unless an FBA seller enters the listing, then it can ignore that rule and price match to remain competitive against FBA sellers). Other than that, this repricer is great! It's extremely easy to set up and you can quickly set your MIN and MAX prices and rules and focus on other aspects of your business. Their customer service is also very courteous and helpful.
