"The dictionary defines a bargain as "a thing purchased or purchasable cheaply." That's fine as far as it goes. What the dictionary fails to say is that a bargain is a bargain only if you actually want it. Every home has its share of articles bought for a song but never used. Here are two kinds of bargains to shun: The Impulse Bargain and The Never-Again Bargain."
