Volume pricing
The highest eligible tier sets one unit price for the selected quantity.
Public interactive demo
Move through exact fictional values and watch volume pricing, adjustment modes, total limits, rounding, and the estimate breakdown stay synchronized using the verified version 0.4.0 frontend.
Fictional print-project example
Change quantity, stock, artwork review, and rush production. Every input stays in this page; nothing is submitted, stored, or transmitted.
Interactive fictional estimate
Unit price: $0.60 from 100, $0.42 from 1,000, and $0.28 from 5,000.
Fictional planning estimate only. Values do not create an order or payment.
All values are fictional. The verified product script performs every calculation locally.
Deterministic rules
The live proof uses the same public calculation API as the estimate total, so the explanation follows the product result rather than approximating it.
The highest eligible tier sets one unit price for the selected quantity.
Paper and artwork add fixed values; rush production adds 20% of the flat subtotal.
The result rounds to the nearest $25, then stays absolutely within $360–$2,490.
Print view removes surrounding demonstration content and estimator controls.
Demonstration boundary
The component performs deterministic arithmetic only. It does not create accounts, save visitor choices, place orders, process payments, set cookies, load remote resources, or call outside services.
Local demonstration
Set quantity to 100 to see the absolute $360 minimum after rounding. Set it to 10,000 to see the absolute $2,490 maximum. Use the middle tiers with both options to verify percentage math.
