Hello Kenny - some clarification seems to be needed re: some financial metrics.
1. Gross profit = revenue - COGS
2. COGS = price paid to manufacturer + transportation costs from manufacturer to the warehouse and from warehouse to customer
COGS does not include warehouse rent and utilities - these are operating expenses.
Hopefully this makes it clear that my reply to your other comment was in good faith and not a straw man. The metric you proposed is not a good metric. Amazon cannot function if Gross profit is 0 --- because it would not be able to pay for the rest of the stuff it needs to function: executives, software developers, warehouses. Saying all the expenses not included in COGS are discretionary is just not true - some of theses expenses are essential.
