Datebox · Locked prices for Shopify stores
Customers pick a day from the ones you really work — and Shopify's own checkout refuses an order whose day has closed, filled up or passed your cut-off since it went into the cart.
Only the days you work
Closed days, holidays, your cut-off and a full day never appear in the picker at all.
Enforced at the checkout
The check runs inside Shopify, not in your theme, so an old cart link can't bring a blocked day back.
Your day, on one page
A calendar of everything due today or this week, by time slot, ready to print and take with you.
Works on every Shopify plan — no carrier-calculated shipping needed. Free plan available.
