Meaning
The kanji 割 on a square button, meaning to divide or cut in Japanese. On price tags it means a discount, a cut from the normal price.
Shops and shoppers use it for markdowns, coupons and flash sales: “Everything in store 🈹 this weekend” In Japanese the same character also counts tenths of a price, which is how discounts are often written there. Pair it with 🏷️ or 🛍️.
