Authoritative product price, promotion, availability, payment choice, and order total are confirmed before an order is placed.
Product information
Maevelle publishes the current product details, available canonical variants, and customer-facing size information held by the commerce system.
Payment
Cash on delivery and manual mobile payment behave differently. Checkout and confirmation explain when payment is due and what information is required.
Order changes
If stock, price, or promotion truth changes before submission, checkout asks you to review the updated order rather than silently accepting stale information.
