It says on their site that they offer custom sizes and to contact customer service for prices which I did. They informed that the size I needed was the same price as their standard sizes, but needed to be ordered horizontally instead of vertically. I more than specified this in my order. I received my order fairly promptly, but of course it's vertical instead of horizontal. I have contacted customer service 5 times, and responded to my original email notifying me that my order has processed. It appears that the only way to get a response is to post their lack of response on here.
