You can redeem your coupons by entering the coupon code on the Redeem code page.
・How to redeem your coupon code
1. Create an account (free) if you are not a BookWalker member yet
2. Sign in and access the “Redeem Code” page (More (Profile) → Redeem code)
3. Enter the coupon code (e.g. vfz8upvttrzcfj — example only) and click “Redeem”
4. If the coupon is able to be used, the effect will occur immediately. Depending on the coupon, it could be activating a deal for a discount or coin back on your next purchase, or adding coins to your account, or adding a product to your account. If the coupon cannot be used then a message will be displayed explaining why, for example if the coupon code was already used more than the maximum times, or the code has expired, etc.
