Choose which customers can buy a product, and from which date. Each window names who may buy, using customer tags, and opens at midnight in the store's time zone. The product stays visible. The product page shows the schedule you write and hides or dims the buy button until that customer may purchase. Cart and checkout block the order and show your message. You can require sign-in, set a minimum or maximum per order, and set a last day to buy. Point of sale orders are not blocked.

• Purchase windows that open to chosen customer tags on a date you set.
• Cart and checkout stay blocked until that customer's window is open.
• A product-page schedule in your own words, beside the buy button.
• Signed-in customers with no tag can buy from a date you set.
• Checkout messages and the purchase schedule in each language you add.
