In busy seasons and during promotions, the storage restrictions become more restrictive, meaning Amazon monitors how much inventory can be stored. The purpose of these monitoring right limits is for Amazon to keep up with the restock limits of other vendors and to avoid excess inventory in a warehouse that would incur high storage fees for everyone. 

Tools to Monitor Your Restock Limits

In Amazon, there are tools available for sellers to help keep track of their FBA restock limits.
