Every year just after Christmas the January Sales start. All the shops reduce their prices and for two weeks, they are full of people looking for bargains. My husband and I do not normally go to the sales as we don’ t like crowds and in any case are short of money as we have to buy lots of Christmas presents.Last year, however, I took my husband with me to the sales at the large shop in the center of London. We both needed some new clothes and were hoping to find a television set. When we got to Oxford Street, it was so crowded that we decided to split up and meet again at the underground station. So I left my husband and started looking around the shops. Unfortunately all the clothes were in very large sizes and so were not suitable for me. But I did buy a television at a very cheap price, so I felt quite pleased with myself.When I arrived at the station, my husband was not there. So I sat down in a nearby cafe to have a cup of tea. I quickly finished my tea when I saw my husband and went out to meet him. He looked very happy. Then I saw he was carrying a large and heavy cardboard box. "Oh, dear!" I thought. Yes, we had no new clothes but two televisions. We shall not be going to the sales again. In this passage, the word "bargain" could best be replaced by "something () ".
