There are essentially 4 ways to formulate your offer:
1) A product or service you can offer worth at least ¥10,000, such as a demo lesson or free consultation. However, it should be special and exclusive.
2) An exclusive discount on services that requires a purchase, such as a straight 33%-50% off on services, a two for one, or a three for the price of two deal, etc.
3) An exclusive discount on purchases of goods that requires a minimum purchase, such as a ¥35,000 product for ¥25,000, etc.
4) A volume purchase of small items (under ¥1000) that results in member savings of ¥10,000 plus tax. Great when showcasing your gift items. This could easily apply to restaurants that host parties or offer takeout. They can offer a variety of dishes at a special rate, which showcases their menu.
