One day Mrs White took Trudy and Ben to go shopping. They went to the supermarket in the new shopping mall(购物中心).
"Why do you buy things here, Mum?" Trudy asked.
"Because they are cheaper than those at the corner store," Mrs White said. "Help me check(检查) the prices."
The Whites were not wealthy(富有的) and Mrs White was always careful with her money. She looked carefully at the prices of things. She bought some groceries(杂货) in the supermarket.
When they got home, the children said, "We don't think you saved money by 
going to the supermarket there."
"Of course I did," said Mrs White, "everything was cheap there."
"We know," said the children, "but we came home by taxi because we had too much to carry. The cost(花费) of the taxi was more than the money you saved!"
Mrs White added everything up and found her children were right.
"Well done," she said, "next time we will do shopping near our home."
