Due to the overwhelming response to our new hardware offering, we have experienced some delays with shipping. That said, our goal is to have newly placed orders delivered in September, but we aren't able to guarantee delivery within two weeks. Keep an eye out for your shipping confirmation email which will be sent once your reader has left our warehouse. If you'd like more information on your specific order, please reply to the order confirmation email you received to reach our hardware store directly.
