I wrote short post on ” Why Amazon Repricing Tool DOES NOT always work ?” back in October and Dave from UnderstandingE recommended Feedvisor –
“I wouldn’t tar all repricers either the same brush, some are very much price and raise to the bottom driven, however some are much more intelligent.
FeedVisor for example have a self learning algorithm which takes into account all buy box factors, not just price and they will get you not just the buy box but the highest possible price you can sell at to maintain it.
Hence the example you have pictured above, the buy box seller could be using FeedVisor or something similar and they win the buybox even when not at the bottom price.”
Feedvisor claims to be fully algorithmic repricing solution on the market today, enabling you to continuously and consistently win the BuyBox without sacrificing your profit margins.
Instead of repricing your products based on your competitors’ prices, Feedvisor understands how the Amazon BuyBox works, and is able to reprice your products based on maximum profit, optimum sales, or any other business goals.
I will try this tool sometime soon and reading a “Buy Box Bible” an refreshing my memory. May be you can give it go !
