Ralph Lauren is having their seasonal sale starting on Thursday, September 29, through October 10. The sale applies both in stores and online. Use discount code RLGIVE2011 to get 25% off your order.
I should also point out that 10% of the net proceeds during this sale will go toward their charity fund to fight cancer.
ADDING: It also will apply to Rugby, too. (Thanks to edwinhu for the clarification.)
