Price and availability live in one place: the store¶

The store (store.embeddedera.com) is the only place that states a retail price, a quantity price, shipping cost, stock or availability. Every other page, ad, post, email template, printed insert and instructions page links to the store listing instead of repeating them.

Product pages, the QR instructions pages (e.g. embeddedera.com/cricket), the product wiki, ads, social captions and printed material: describe the product and link to the store; no $, no "in stock", "coming soon", "sold out" or ship-by dates.
The store listing and its checkout handle price, quantity breaks, shipping, tax and availability.
Internal records are not "places" in this sense: the ERP keeps sale price breaks for invoicing and audit, which must mirror the store and should be copied by the store↔ERP sync, never typed separately. Notes and logs may record a decision ("price set to $24.99 on 2026-10-06") as history.

Why: one place to change, so nothing goes stale or contradicts the checkout; the owner's explicit best-practice call (2026-10-07).
