Problem
Private label brands (aka retailer brands) usually sell for about 20-25% less than national brands (aka manufacturer brands), but they usually are 10-15% more profitable. Recently, some supermarkets have started to go "up-market" with "premium" private-label brands that compete more directly with the national brands.
Explain why you agree or disagree with the decision of some supermarkets to sell "premium" private-label brands?
