that is why ingon ko sobra pa sa tuyok....
because suppliers gives 30-60 days term.... so when you pay by credit card and as you said wait for the bank to pay... you can still turn around the money..... because there are more days left...
it is only right that appliance store gives discount...... because the suppliers are more than willing to wait for 60 days to get paid....
so the retailer can use the money for 60 days..... and the supplier won't mind....
