With effect from 1 February 2017, the Hachi rebate you earn will expire 60 days from the date of issuance.
E.g. Hachi rebate earned on 1 February 2017 will expire on 2 April 2017
For any purchase where balance rebate is not used in full, the new Hachi rebate earned will also have their expiry tied to the current balance rebate's expiry.
Unused Hachi rebate will still be forfeited upon your Hachi membership expiry.
