Read the source and quantity method
A small manual review of public retailer and supplier web listings. Review date is when StackX read the source; it is not a store-verified quote date. No automated price refresh or prior comparable edition is available.
USD, listed single-unit material price. Tax, delivery, installation and project-specific discounts are excluded from calculations. Alternatives are separate products with different system requirements; their panel prices alone do not establish whole-system savings.
Material area is divided by published sheet, roll or bundle coverage and rounded up to whole units. Slab order volume is rounded upward to 0.001 cubic yard; actual supplier minimums and order increments still need confirmation. Displayed decimal areas are rounded only for readability.
Changing a field creates a private assumption. Public prices are a small convenience sample, not an average, paid transaction dataset or community quote network. No market forecast or historical price change is calculated from this first edition.
