YouTube videos on saving money

Thought I would try something different for a change.  Since YouTube has videos on just about any topic, I trolled it for consumer-related ones.  I came across this one about saving money with coupons.  There are many more like it, some professional looking, some broadcast news clips, and some more folksy in nature. 

This is short, just over two minutes, but one, which I haven't viewed yet, is over 20 minutes.  I am curious as to how much detail is involved with it. Perhaps they take us on a ride to the actual store, including drive time?

Enjoy
