Mr Thrifty's How to Save Money on Absolutely Everything

Mr Thrifty's How to Save Money on Absolutely Everything Customer Review: Didn't save me any money
Being rather frugal myself, I purchased this book, hoping to live life even more economically than I already do.
On the early pages the book states how it will soon save you at least the cost of the book, in your more thrifty lifestyle (unless you are reading the book in the shop, or borrowed it from a library!). But this has not turned out to be the case for me.
There are some valid points in the book, but I find the applicable ones, which could potentially save me money, are impractical. For example, details are given of a website that offers lots of freebies. However, this website bombarded me with lots of unwanted emails once I signed up, and I have yet to take advantage of any of the offers there.
There are also some tips that I strongly disagree with in the book. It advises against paying any money into a pension for instance, and suggests alternatives as to where one could invest the money. But I do not agree with this.
Any real money saving tips for me were just a pure matter of common sense, which we should all have an ounce or two of (this supposedly being a common sense book!)
