Super market

In this afternoon, I said to Joanne."I have to save money, so I don't want to pay so much money for my lunch. But sometimes, I feel a hungry in the afternoon." And Joanne said me, "That's not good for your health. I know the cheepest super market in Cambridge. It's very nice! I always go to the super market, and I buy my lunch." And then, she told me the price in the super market. I'm very surprised that the price is so cheep! I asked her the way to go to the super market.
After I came back home, I was talking with my mother in the internet. Then, Joanne called me. "I'm in front of your house now, and I'll go to the super market. Shall we go?"
We went to the super market together, and I bought some fruits and vegetables and breads for my lunch. These are enough to eat for a week! And the price is cheeper than my usually lunch!
