Social media sites like Twitter and Facebook are great sites to search for great promotions, but be suspicious if they are urging you to just click shortened web links simply because you will not really know if you're going to reach a reputable dealer's web page after you click on it. If you are doing transactions with an unfamiliar merchant or online shop, verify with the Better Business Bureau or your city or regional consumer protection agency to know who you really are transacting with. Rivalry between businesses results in their necessity of continually bringing in income no matter what. Thus, they provide showcases so as to entice people to purchase their goods. Transacting with a vendor who does not want to be recognized should be shunned at all cost as they are likely scammers.
