Youtube is not only #3 site by visitors, but perhaps the more useful than #2, the Facebook, and second only to Google. All of us in our life time (or Youtube’s) saved some money by using this site.
Youtube is probably a largest source of money-saving information on this planet? Youtube videos alone can save $100 – $500 per month depending on your spending habit.
Yesterday SMB wanted to practice a song with karaoke, the cheapest price I could find for the karaoke was $1, but pleasantly enough she suggested a Youtube search. We found it and thus saved the money!
