If the Buy Box was suppressed months ago, possibly due to the absence of FBA sellers or higher prices at the time, I currently have a 60% ROI based on the lowest price of the year.
My question is: If I start selling at the previous lowest price set by an FBA seller, is there a chance that the Buy Box could be unsuppressed, or that I could start seeing sales?
As long as the BSR is okay and Keepa tabs show stock drops, you should be able to sell. There is no issue. Yes, if the price returns to the point where the Buy Box was unsuppressed, there is a chance it could become unsuppressed again.
From personal experience, if you match or lower your price to what the FBA seller had before, there’s a good chance the Amazon Buy Box could be unsuppressed. Using FBA helps too. While there’s no guarantee, it increases your chances of getting the Buy Box and making more sales.
