At each Thirty One Ice Cream store, a campaign will be held for 11 days from September 13th to September 23rd, where each "double" size will be "31 (Thirty One)% OFF".
"31% OFF every day" for 10 days!
"31% OFF every day" for 10 days!

The target menus are "Small Double Cone / Cup" and "Regular Double Cone / Cup", and the discounted prices are 275 yen and 400 yen, respectively. I want them to enjoy it during autumn holidays (not held at some stores).

At the same store, a campaign "Challenge the Triple" that allows you to upgrade "Double" to "Triple" for free is being held until August 30th.
