Expired Jungle energy Bars

Bought a jungle energy bar sometime last year and ate almost all of it, only to realise that it has expired. But decided that since I have eaten so much of it and as disgusted as I was, I decided to let it go. Unfortunately for me again on the 11/02/15 I bought the same bar again and as I was about to bite it, it was as hard as a rock and then I remembered to check the expiry date and to my suprise it had an expiry date of 15/08/2014, so I wonder, how come such a big store that is considered a baby company sell expired products. As a customer I am very dissapointed, I could be buying this for my child and then what, cos chances are they will just eat without looking at the expiry date. This is a serious health hazard!!! Really mad and dissapointed!!!
