Worked example
Charging $8 when fulfillment costs $11 creates a $3 shipping subsidy per order. Across 100 orders that reduces profit by $300.
What to do with the result
Treat free or subsidized shipping as a real order cost rather than assuming it disappears because the customer does not see it.
Frequently asked questions
Is free shipping really free to the seller?
No. The shipping cost still has to be absorbed somewhere in product margin or pricing.
Can charging shipping add profit?
Yes if the amount collected exceeds actual shipping cost, subject to platform rules and customer expectations.
