I made a $0.96 profit selling at the current price of $9+ USD. However, when the low inventory level fee kicks in on the 1st of April, if I have days in stock 28 days or below, then I will be charged a low inventory level fee, which can be up to $1.11 depending on the size and historical days of supply (see the image below).
Now, I am going to increase my minimum to 13 so I can cover all fees and make it worthwhile to sell this ASIN (I don’t like making pennies). The Keepa history and current listing situation are telling me that this is the right thing to do.
They will charge you 1.11 only when your stock will be really low to cover sales for only 14 days or less. It’s calculated on short term (30 days) and long term (90 days). More realistic scenario that you will be penalized for only 0.47 (21-28 days).
