I went to supermarket with my wife last Saturday night, we just walk in at random and have no shopping list on our mind though. But our attention was attracted suddenly by a promotion show the very moment we entered,some young girl was singing and dancing to sell a new brand of beer. That's interesting, buy 5 bottles and get 1 free. So we just bought 5 and got 6 in hand.The 6 bottles are still in the refrigerator.I might need to cook home to drink those.
