Frequently asked questions

How do I use a Kinship promo code?

Copy the code, go to kinship.jp, add what you want to your cart and paste it into the "promo code" or "discount code" box before paying. Check its conditions first: minimum order, first order only or excluded products.

Do these codes really work?

Each code shows when it last worked, based on anonymous checks by people who use Kupoki. Codes that stop working drop off this page on their own.

Does Kinship offer cashback?

Yes: with the Kupoki extension you get back 3.5% of what you pay at Kinship. Activate it before you buy.
