This website runs on the catalog pattern described above. Its prices are read from a database on every visit and written into the page and its search markup in the same step, and the price editor sits behind a sign-in that only the owner's email can pass. Under the hood shows how, and the X-ray toggle in the header lets you see the price data behind any price card.
Shaun also built and runs a subscription software product with a catalog, Stripe payments, a large database and an AI connector. The pricing pattern here came from that product.
Card fees are Stripe's, not ours: the standard US rate for a domestic card was 2.9% + 30¢ per successful charge when we checked on 27 October 2026 (Stripe pricing). They are paid from your own Stripe account.
