Convenience stores are more than just the place to pick up a snack and a beverage. They are also the place to go to pay bills. That's right, you can just stroll in with your electric bill, the clerk will scan it, and then you fork over the cash. We tried using a credit card once, and that was a mistake we didn't repeat again. Cash is required for almost everything here. Of course some companies will let you do an automatic deduction from your bank account, but for the ones that don't, the convenience stores always have an ATM too, so you can take cash out on the spot to pay your bill. I personally prefer paying bills on-line, but this method does encourage impulse purchases, like trying the latest seasonal flavor of KitKat bars.
Happy Birthday E-Money!!
