When you order a dress, but the shop sends you a blouse. When you order a Christmas tree, and end up getting something that looks more like a dead trunk. These stories happen all the time. Many consumers have wasted their money buying junk just because they go for low prices and believe in eye-catchy images and slogans. More importantly, goods such as counterfeit money, weapons and explosives and drugs are all advertised online. Handling advertising violations on cross-border platforms remains difficult. In the meantime, online purchasing depends much on the seller being responsible and the buyer having a bit of luck./.
