So I've been thinking lately, companies pay a lot of money to run advertisements on T.V, yet I have very very seldom ever purchased something because I saw it on T.V. I really can't imagine a person who hears an advertisement for Sham-wow and really decides they want to buy that product. So guys, have you ever bought something because you saw a commercial for it? Do you think its a gamble for companies to spend so much money on advertising their products? Am I a complete idiot who knows nothing about how business works?
