Using a tool to adjust your product prices to the current market situation is a no-brainer. A human cannot set prices better or more accurately than software, nor do business owners have the time to track and evaluate hundreds of price changes per day for every individual product and adjust the price accordingly.
About 90% of the conversions on the product detail pages on Amazon take place via the Buy Box because only very few customers even register that there is a second “box” displaying other sellers further down on the product page. The competition for the small yellow box is correspondingly high, especially when selling Wholesale.
