Stockout on Purpose?

(9/23/2013) Do you think sometimes business let stockout happen on purpose? Yes, it can be. Lululemon "circuitously admitted" that the plus-size clothes do not belong to their target market. Plus size customers cannot easily find their clothes in Lululemon because there is not much in their stock. If you are lululemon's customer, have you noticed that there is no much plus-size clothes there? Is this market positioning a correct strategy to business? What about Lane Bryant's targeting on plus-size market?
