Game Your complete Out Of Stock retailer.

This is the third time that I have experienced this problem with game. They always advertise products but never have stock available.I went to the store in Canal Walk to go buy the advertised Hi Fi last week ,when I got there there was no stock,went again to today and the same item is still on promotion but no stock ,so how do you advertise Low Prices and Promotions when there is never stock availible,Game specials is a complete waste of time I waste my petrol and time everytime I go to Game for one there specials.
