There are lots of horrible stories that explain how people in Australia get hacked and their bank got empty after making an online transaction and due to that there are many people who are now avoiding online shopping just because they have heard that kind of stories.
There certainly are some danger or we can say lots of danger, but it does not mean that all sites and all sellers are scams.
Many of the legit sellers and the sites that are opened by the bands and popular stores still are working at their best and they offer high quality goods and services, they also back up their products so that their customers feel easy and relaxed when they shop online.
For this reason when you have to buy things like htc, asus, smart watch, projector and dash cam like products you need to be sure that you are going to the right seller and there are no previous records of fraudulent activities or any negative consequences linked to the site.
Further you may keep in mind that when you have an access to cheap tv, cheap galaxy s7, xperia, asics kayano and security camera you should know that you should not go for the least prices and make sure to look for reasonable prices which are acceptable. The reason behind it is that when you go for extremely cheap prices you may get into trouble just because you don't focus on the quality and just take the price as your basic and final criteria.
You may also consider not opening the sites which are full of lame and useless content and you should know that such sites are only there to scam others and they never will be giving you the products or things that you have paid for. Make sure you don't invest in such cases.
