An initial promotion running from late August to early September focused on discounted food items, such as Maruchan Yakisoba and Heinz soups, alongside daily necessities like Pantene shampoo and Bold laundry detergent. 

A subsequent promotion scheduled for mid-September shifted focus toward bulk purchases of private brand products under the ‘Minasama no Osumitsuki’ label, including curries and ramen.
