Does anyone know of a place to get rubylith locally in the Northern Virginia area? Or a website that that sells it and has cheap shipping? The only place I have seen online with it is an astronomy/telescope site, and they charge atleast 10 bucks for shipping. For a small roll of it costing 10 bucks, ugh. I'm kind of surprised adorama or freestyle don't carry it, unless there is some generic brand I should be looking for? Thanks.
