i didn't know how much i short of
they oredi punched in liao
arbo i will anyhow buy something lor
i didn't know how they count lor
becos i used my $10 voucher to buy 1 X $12.90 item
i thot that is 1 transaction
then i used $80 vouchers to buy $105++ items with 20% bd
discount (which is eighty over dollars lah)
but their machine quite clever
can put all into 1 transaction
so in the end expenditure is $88
i think the metro bapok dunno how to count
so he never advised me to top up
i also nvr think of it
but it's ok lah
he was very nice
gave me samples of vitamin capsules 
becos i said your compexion very good what you use ah?
he said the vit C range
