little rip-offs can add up

In the past week I have saved myself $5 a month plus over $7 in fees that I shouldn't have paid. This was simply from glancing at two statements - my mobile phone bill and my Myki account - and feeling something wasn't quite right. Whilst this does not add up to a great deal of money in the grand scheme, it has made me wonder how many other organisations charge accidental or incorrect fees somewhere on some obscure line on any of the many statements we receive.
