Carters just announced a 50% off sale and released a 20% off coupon for August. No word on when the sale ends (Carters almost always has something on Sale), but the coupon is good through August 25.
Like Oshkosh, Carters has their own version of the Play Card. They give you "Gift Checks" It works the same way as the Oshkosh Play Card. More details about Carters Version of this saving opportunity (or perhaps it's really a wolf in sheep's clothes, making it a spending opportunity...you decide) can be found here.
