The rows of a multipack price list can also have a daily price, so that the system can calculate the price of the multipack according to the actual number of days of validity. An example will clarify the purpose of this option:
Winter price list valid from 01/09/2016 to 31/05/2017: the cost of the multipack will be 2£ a day;
Summer price list: valid from 01/06/2017 to 31/08/2017: the same multipack will cost 2,50£ a day;
therefore if the multipack is sold on the 25th of May 2017 with a thirty-day validity, the system will calculate the cost of the multipack in the following way:
- from 25/05 to 31/05 --> 2.00£ x 7 = 14£ +
- from 01/06 to 24/06 --> 2.50£ x 24 = 60£ =
total price: 74£
During the sale the system will display the price-list rows that offer this option and will show the cost of each period. The start of the validity it is always based on the current day. In case the validity of the multipack is different from the current day, it is necessary to specify the date before selecting the required row of the price list.
