RK Delivery Date Picker lets customers choose a delivery date and time on product and cart pages. You set timezone, cutoff, closed days, and slots in admin. Same-day countdown and optional ASAP are included. You can require a window before checkout. The chosen date and time save on the Shopify order. Setup uses a theme app extension—enable the embed and add the picker block. No theme code paste. Works with Online Store 2.0.
