My sister received an email for $15 off (must spend $49 or more). Shipping is also free once you spend $49 or more. What great is you can have your total at $49, which activates the Free Shipping, and then add the promo code. She wound up paying $37 and still got Free Shipping.
This is a targeted email as unfortunately I didn't get one myself, so check your emails!
The email title is "We Miss You". So if you didn't get it yet, and you haven't ordered in a while, be on the lookout.
