Do not treat a wish list notification as an order confirmation. Consider whether the saved entry belongs to the same seller.
Confirm the intended hold period in clear date terms. Base expectations on the hold arrangement the seller explicitly accepted.
Ask the seller about any element essential to your intended use. Treat the seller's confirmed inclusion list as the basis for your expectation rather than illustrative context.
