Comment by ekropotin 3 days ago But the cost of Amazon Prime have to be factored in as well 4 comments ekropotin Reply bigstrat2003 3 days ago Only if you weren't already paying for Prime. If you were, then it's irrelevant as this usage adds no marginal cost. moralestapia 3 days ago "If you already pay for shipping then shipping adds no marginal cost." OkayPhysicist 3 days ago well, yeah. That's what the phrase "marginal cost" means: if it costs $x to do something N times, and $x + $y to do something N+1 times, $y is the marginal cost. happyopossum 3 days ago No, for anyone considering doing this it does not have to be factored in as it’s a sunk cost.
