Pricing
Cost-plus: add a markup (or margin) and print the price.
Cost-plus is the oldest shortcut in retail — take cost, add a percentage, ship it. Use markup if you think “on top of cost,” or margin if you think “share of the ticket.”
It ignores demand and competition. Fine for a first tag; check break-even and fees before you treat it as final.

How it's calculated
Same cost, different language. 50% markup on $20 is $30 (33.3% margin). 50% margin on $20 is $40 (100% markup).
markup path: price = cost × (1 + markup%) margin path: price = cost ÷ (1 − margin%)
