Order remained unfulfilled for a period of over three months. Sent numerous inquiries to their support email over this span of three month, which is one of the two primary contact methods that they continue to request that people reach out to. Was told to contact USPS for more information on the status of my order when the tracking information I had received indicates that they were still awaiting the items. Investigation into their Twitter feed indicates that this is a common occurrence. Buyer beware, recommended that users use PayPal such that they can solicit a refund in the event that their order remains unfulfilled.
