Not in sync

Not one but 2 items wrongly priced - and, yes, you've guessed it! not in my favour. After a tedious wait whilst one of the assistants went to check codes and prices, I did get an override and refund, but why do I have to check each and every item on my till slip? The excuse that "Some times we don't know that new stock is a different price" is just not acceptable. Get your stock and till point prices in sync!
