Delivery and pickup have their own sections with customizable settings:
You may select what type of period to offer: date, date & time, or date & time slot.
Each weekday can be set up separately with its own order limits, cutoffs, and lead time.
Specific dates/holidays can be easily added to the blackout list.
Delivery and pickup can be enabled based on the specific cart or products attribute.
The orders containing the date/time selection can be assigned with a specific tag corresponding to the delivery or pickup option selected.
