As per request. I have added a list of shops and the dates which you can buy ROYCE' chocolates in the Kanto area. It is much cheaper that ordering directly from the shop since you don't have to pay for the shipping fee which is 1,100yen. If you have the chance, please stop by! They will definitely have this month's special edition Nama chocolate "calvados"!

You can see the list from the top menu or here.
