GG UOBONE
GG GPMC
It was good while it lasted...
for me I don't really care about the 5% extra rebate for topping up UOB X Grab... it's the prudential insurance monthly premium paid via UOB One card that really stings (or stinks), since it will no longer count as card spent for card rebate (3.33% for $500).
but there's no other card out there that accept insurance payment and can give rebate at the same time.
as for GPMC, there's no reason to top up anymore. or to use the card.
