Almost everyone has gone shopping online. We can buy any items online and they can be delivered to you in just a few days or even within 24 hours. In that case, we even buy a tube of toothpaste online instead of going to the grocery stores near our apartment. As more and more people tend to go shopping online, the express companies also try their best to boost the speed of delivery by purchasing planes or building their own delivery systems. All they did makes shopping online more convenient. Meanwhile, the venders online also make more efforts to attract the consumer's attention. Some of them reduce profits to give the consumers more benefits, but some make false advertisements to deceive consumers. The items people received are of low quality, which are very different from what they have showed online. They just want more people to buy those kind of items once so they earn a lot of money, they never think that the consumers would buy the items again. The websites or APP will ban them selling anything online later. Usually, the price of the items are very low, so people often give up trying to get their money back. So, if you find a item whose price is much lower than the same kind sold on other online stores, it's probably a fraud/scam.
