Home-shopping channels often prey on lonely viewers. People who feel alone or alienated can fall victim to sweet-talking order-takers, who may lure them to buy more than they could ever need. Be careful of buying junk as well. Some channels sell-low-quality jewelry, carpets, kitchen appliance, musical instruments and other accessories worth even less than the low price you pay. If you wanted to buy a guitar, you better get one here. Don’t be fooled by shiny garbage. If you would never use or need it, it is definitely not a bargain.
