In a British supermarket, I saw the prices of Christmas chocolate gift boxes being cut dramatically (£1.50 to £0.15, and £7.50 to £0.22). I don't quite understand this behaviour, where the chocolate boxes are sold (presumably) below cost.
I've learned that this sort of strategy could be used to eliminate competitors and strengthen monopoly, but I don't think that's quite relevant for this case. It seems more of a clearance to me. What is the motivation behind such behaviour? Why don't the supermarkets just continue selling them at a low price, but not so low? Is it simply for saving warehouse costs?
