At present, the more popular fraud mode is: make a phone call first, online, and say that you will be given something for free, so that you can pay a freight fee (or certification fee, production fee, tax money, handling fee, etc.). ) and collect it by express delivery, and then generally send a prepaid card, which is greater than the freight denomination.

For example, let you pay the freight in 99 yuan, xxx and other items and a 100 yuan prepaid card. .
