Re: ?WTF?
Stella Artois used to do all that they could to keep the price of their lager high in shops as "24 bottles for £5" offers might cause a short term increase in sales but in the longer term were considered to erode the "reassuringly expensive" reputation (and the connection with "high quality" which got associated with that) that the were keen to maintain!
So, one reason to keep prices up is to avoid the brand being seen as a "cheap value brand" if they want it positioned as high quality.
