People can buy not only goods, but also all kinds of services on group purchasing sites.

人们不仅可以在团购网站上购买商品， 还可以购买各种服务。

In my opinion, we should treat group purchasing as a way of shopping and nothing more.

在我看来，我们应该把团购当作一种购物方式， 仅此而已。

Problems that exist in online shopping also can be found in group purchasing, like deceptive advertisements or poor after-sale services.

网络购物中存在的问题在团购中同样存在，如广告欺骗或售后服务差。
