I listened to the earnings call (q12015) that happened this morning and one piece of information perked my ears and I think you may be interested too. There is an online lululemon warehouse sale 2015 sale slated for Q2 which to my estimations are July/August and a physical warehouse sale may happen later in the year. I'll keep you posted with what I hear.
** Note about this years warehouse sale. Normally the inventory you see at the warehouse sale are pieces we've seen in stores already and excess inventory from WMTM but this years warehouse sale will include a lot of the spring product that was delayed at the ports. Some of those items will have hit stores and been integrated into the product drops but some of that inventory is heading straight to the sale.
