Impulse buyer beware!

There seems to be little care about consistency of stock in stores in Japan. Even within the same store chain, something available at one branch may be absent at another. That can turn buying on impulse into a bad habit, or interfere with anyone who is trying to keep it under control. You`re at a shop that you thought you knew, and suddenly there`s something on the shelf that wasn`t there at the one near your residence.  Something to keep in mind.
