Mos Burger starts delivery service from April

The problem is that 200 stores corresponding to 20% of the total are targeted and the delivery range is within 1.5 km from the store .... Please extend it to about 15 km. Mos Burger full-fledged home delivery, from 300 in April: Economic News: Economy · Money: YOMIURI ONLINE (Yomiuri Shimbun)

The home delivery menu is the same as the shop front, and we have also developed a transportation box with a high thermal retention so that the product will not get cold. The delivery area is set within 1.5 kilometers and the delivery fee is scheduled for 200 yen. As a delivery member becomes "an advertising tower of a shop to develop demand" (Public Relations Office of the company), veteran employees will work as much as possible.

As a result of experiments, it seems that sales have increased by about 10%.
If it increases by 10% within the range of 1.5 km, it must increase by 10% if it is within 15 km distance! (It does not pay out)

Or perhaps it is within range that you can deliver by bicycle?
