Writing about online shopping

It's not surprising to say I'm going to buy something through the internet. This practice became popular since some years ago.* By the way, I bought my notebook (laptop), including others gadgets on the internet. It's pretty safe...I mean, the internet is never one hundred percent safe, but is mostly safe.
Lately a friend of mine told me she buys her clothes from the internet. I asked the predictable question "But what if the clothes don't fit you well?" Then, she said the company could exchange the clothes or even give her money back without a fee.** I didn't know that, so I asked myself if it would be better buying clothes online because usually I don't like to buy clothes in stores. Today I looked up on the internet for some clothes and I think I will give it a try.

*or you could say: "This has been popular since some time ago"

**alternative:  "She told me the company could do an exchange or issue a refund"
