Hello,
You can then implement the following functionality without programming? I want the buyer to be able to select the delivery time, but depending on the mode of delivery slots at me different.
As Nicolas said, there is no option to do that so the only solution will be to directly develop that functionality, which means that some programming knowledge will be required.
Delivery by courier, intervals 14-00-16-00, 16-00-18-00, 18-00-20-00, 20-00-22-00.
Pickup at point of issue of the goods, only the interval from 18-00 to 22-00.
For the moment the solution can be to specify these schedules directly through your shipping methods description.
