The new system is optional and be available with the regular Prime delivery, and delivers all the booked items on one specific day pre-set by the customer.
Users choosing this option will have to pre-set a day in a week, so they can receive all the orders delivered on that specific day. Customers can make bookings until two days before the designated day, and this can be changed whenever they want.
