Expired Goods!

I went to Game at city view mall at Durban yesterday and I noticed that there were various items on the reduced to clear section. I love purchasing discounted products and I immediately get excited. I bought vitamin water which was on special. When I got home I have this water to my aged sick dad. He complained about the taste. I then noticed that the water was expired in September! I was horrified! This had happened before at clicks and I complained and this is happening yet again! I'm really disgusted that a large store like clicks sell expired Goods to customers. I'm really disappointed! I think I should stick to a more reliable store like dischem where I don't experience such problems!
