I just found a nice 25% off coupon code for the Aerie online store. The code is valid when you purchase 2 or more bras before the 1st of February. Bras at Aerie are really cute and reasonably priced ($24.50-$$44.50) so you might want to check out this offer. Unfortunately, the code cannot be used on American Eagle or 77kids products, it is only applicable to Aerie Canada store.
