Can't get 30% off deal from Gymboree.com

[FelicityNYC]

gymboree.com:

I entered the code SPRING2002 but nothing happen to the total amount. Has this deal been expired already, or for new customers only???

I also tried the code NEWBABY2002 for 20% off, but couldn't get any discount.

Does anybody know why?

I used to use the code NEWBABY2001 and LBT1 in January and February. Then, I received 20% off each time.
