Price the five-pack before you promote it.

Write the unit price and order total together

A quantity offer should show what the customer pays per unit and what the whole order costs. Distinguish minimum-quantity pricing from fixed bundles. A five-unit threshold may apply at six units; a five-pack is a specific package.

Using an illustrative schedule of $39 for one, $37 each at two, $36 each at three and $32 each at five, merchandise totals are $39, $74, $108 and $160. Check the same numbers on the product page, cart and checkout.

Look at the cost of the larger basket

Suppose each vial costs $12 and processing is 2.9% plus $0.30. Five vials at $32 produce $160 revenue, $60 product cost and $4.94 processing cost: $95.06 before shipping, labor, tax and other expenses. These are example inputs, not provider quotes.

A single $39 vial under those same assumptions contributes about $25.57. The larger order contributes more dollars, but less per vial. That trade-off should be deliberate rather than hidden behind a discount badge.

• Include affiliate commissions where applicable.
• Account for packaging and shipping subsidies.
• Test discount-code stacking with quantity prices.
• Review refunded and partially returned orders separately.

Choose a rule you can explain

Decide whether quantities combine across variants. State the rule beside the selector. If each variant is counted separately, a basket of three small and two large vials should not silently qualify for a five-unit price.
