Motorola’s existing customers have received an e-mail that gives them a discount on the Moto X. The Moto X will cost $349.99 for existing customers, which is $50 off of the asking price. The e-mail has a coupon code that is exclusive to each user and has to be used during check-out to make the discount available. It is unknown whether the coupon codes can be transferred to other users.
