I have a lot of computer games, and they really cost a lot. The problem is that I've played them too many times already. I heard about the Swap Shop and exchanged one of my games. I'm really happy and I've made a new friend—the boy I exchanged my game with! Now I want to exchange more because it really helps me save some money.

I have a necklace(项链). I've had it for two years and I don't like it anymore. I want to exchange it for some books. I have swapped clothes before, but I think I will have a try at my necklace! It's better than spending money at the shopping mall.

I don't like shopping. I love the idea of Swap Shop and I'd like a skateboard. I've got a football that I want to exchange. I've had it since last year and it's still new. I'm going to try the Swap Shop for the first time.

I want a new mobile phone. Mine's quite old. I've saved some money, but it's not enough. So I've decided to try and swap mine for a different one. I've exchanged some CDs on the Swap Shop. It's cool!
