Valentine's Day is coming. For couples, buying Valentine's Day gifts becomes the top priority, and online shopping is naturally one of the best ways to buy gifts. Because choosing gifts through online shopping not only has a variety of options, but also offers convenience, speed, and the ability to browse all online shopping malls without leaving home. There are also often various promotional discounts and surprises. However, this demand of Internet users is often exploited by fraudulent websites. If not careful, bank account funds can disappear without a trace.
