A lot of people have talked about how they bought something, thinking it was a good buy and turned out it wasn't. In your lifetime, what things have you spent money on, whether it's from an advertisement and you actually felt you made a good investment? (The product actually worked wonders like an ad may have 'promised' that it would) OOOOOHHH how about those products from those infomercials? Yeahh you know what I am talking about. I'm just curious of people's investments, and if you have some things you may have bought that you later found out was a waste of money, feel free to share those as well!
