Keep using when you buy something, so that it just piles up. I find it's annoying, when the cassier says "do you have a TPC"?. Customers should be used to TPC by now, and I myself, I have 2 cards, and one of them I'm getting near 1,800 points, but recently I sometimes use it when I buy stuffs, so it's less than a thousand points now, but I get points by daily shopping at FM as well as paying my expensive softbank phone bill.
The most pain is that, you got to register Yahoo website, and I forgot which yahoo email I am registered to TPC, that I have 2 cards now, but can't conbine into one!!! The registered one's magnet is becoming unstable, so that I can't use it to pay with for sometimes...
What can I do...( ̄∇ ̄)
