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.
