yeah HTSC does carry 30% but it shows up and dissapears quick. They really don't like to take special orders on fuel there for some reason though. I asked the same and got the same answer that I'd ahve to buy a case for them to order it. But now that I think of it I shoudl ahve just boguht the case anyhow because last time I was there I snaged 3 gallons of 30% OD and I think a case is 4 gallons.
