What a discount really costs
Sale price = price × (1 − discount). A 1,000 product at 20% off sells for 800.
A discount comes entirely out of your profit. If that product costs you 600, profit falls from 400 to 200, half of what it was, from a 20% discount.
That is why a small discount can need a big jump in orders to pay for itself.
