Exact date is 1st of May which is 2 days from now.
I have just called the customer service to redeem AEON RM 50 voucher, for 14300 point.
If you care free, you may go to MENARA MAYBANK, KLCC, 1 UTAMA and GARDEN to redeem the voucher which will be lower, no need postage.
If I am not mistaken you need 12000 point to redeem for RM 50 voucher.
