    There are many ways you can save money at the supermarket . Here are some of the best:

    Make a list and follow it.

    The list is about your needs: the notebooks you're out of and the food you need for daily meals. When you buy the things that are not on the list, you are wasting your money.

    Compare the prices.

    The biggest package isn't always the cheapest. Sometimes it is cheaper to buy in bulk*. So it's useful for you to compare the prices.

    Ditch the basket or cart.

    If you're going to the supermarket just to pick up milk and bread, don't use a basket. Baskets let people to buy more. Only use a basket or a shopping cart if it's really necessary.

    Make one large trip instead of several small ones.

    Each time you enter the supermarket, you get another chance to spend. By reducing the times of your trips, you're saving both time and money.

    Shop when you are full.

    If you go to the supermarket for milk on a Sunday morning without eating breakfast, you are likely to come home with bread, sandwiches and orange juice.

    我回到四叔的书房里时，瓦楞上已经雪白，房里也映得较光明，极分明的显出壁上挂着的朱拓的大“寿”字，陈抟老祖写的，一边的对联已经脱落，松松的卷了放在长桌上，一边的还在，道是“事理通达心气和平”。我又无聊赖的到窗下的案头去一翻，只见一堆似乎未必完全的《康熙字典》，一部《近思录集注》和一部《四书衬》。
