The rebate you earned will automatically be saved in your account.
Any available Hachi rebate will automatically be applied to your next applicable purchase in full.
You will still have the option to not use all your available Hachi rebates and amend the amount of Hachi rebates to be used.
However, doing so will cause the new rebate you earn on the current transaction to expire on the same date as your current rebate expiry.
You may redeem a partial amount of your rebate. Any remaining rebate amount that is not utilized will be brought forward to your next purchase. Unused Hachi rebate will be deducted upon the expiry date or when your membership expires.
