I forgot to apply my promo code, can I use it for an order I already placed?

Promo codes must be applied at checkout. Unfortunately, if you forget to apply a promo code, it is not possible for us to retroactively apply it. If you forget to apply your promo code at checkout or find a promo code after ordering, you can either save the promo code for a future order or cancel your order and reorder with the promo code applied.
