Quoting ma ♥:" Are you signed up for emails from them? Did you get the 'mystery event' coupon code? Can I have it? Mine is only 20% off but I want to find one for more if it's possible!"
I am signed up with them, but I only get emails with coupons from time to time.
I was able to find some printable coupons & coupon codes for more than 20% off online.
Found this 30% off code G9J2012 here: http://www.printablecouponsbirthday.com/childrens-place-printable-coupons/
Let me know if it works. It says it works until 18 Nov 2012, but I doubt it..
