Nan bought milk, eggs and bread more than once a week when she was single. Well, usually she did. She bought bread and milk quite often, but since she usually bought a dozen eggs, she didnâ€™t need to buy them so often. Her real problem was when she bought vegetables. She couldnâ€™t buy them in small amounts, so she always had more than she needed and the vegetables often spoiled. Then she had to buy more.
