Shengliver’s Note: Zhang Shuchen the teen is shopping-wise in the digital age.

Nowadays many people buy their computers and mobile phones on the Internet. Of course, it is convenient with what you desire at your fingertips. However, you might fall prey to a scam if you were not wary enough.

On some shopping websites, the prices of their PCs on sale are extremely low. You might believe their merchandises are competitive. Remember: There is no free lunch whatsoever in the world. Usually, the low prices are just one of their means to take the customers for a ride.

I befriended a boy at a tech forum. He shared with me a piece of software, with which you could alter the specifications of a computer’s hardware such as the CPU and Memory. Though the hardware does not change at all, the manipulated figures will show that your computer has better components than it does. A lot of unscrupulous businesspeople use this software to tamper with the configuration of their electronic goods so that they could chisel their customers out of their money.

Therefore, please choose to shop on some trustworthy websites, such as Amazon, Jingdong and Suning, when it comes to purchasing high-end digital devices. Always bear in mind that there is no free lunch on earth. Every meal served on the table costs: if you do not pay, somebody else does.
