Whenever I buy a game usually I have researched it and made a decision to buy. I go to the store, don't browse, pick up the game and leave. But, every now and then I make an impulsive buy. For example I went to Wal-Mart and bought both Bulletstorm and Portal 2 on a whim yesterday. Sometimes I regret impulsive buys but other times I don't. What about you?
