Last week a major dairy in Australia apologised but due to the price of diesel...they were forced to raise the price of a litre of milk by 5c...the NEXT DAY...Coles Supermarket raised the price by 20c!.... I raced off to IGA and Aldi and stocked up on milk at the old price...a week later... I was in Woolworth... Coles biggest rival...and was surprised to see a big display about their milk being the old price...so I bought a load more....BUT at the checkout I was charged 20c more per litre... I made them check...got an apology and a refund...but how many people were ripped off and didn't notice?...ask for a receipt and check it....there is a reason they make massive profits....
