My mistake for taking them for the "square" type window frames. You should still be getting "Extrusion" for those as long as there is no "foreign material". As for not having a published price list, you might want to check State law. They might be required to have prices published. One yard here doesn't have a handout with prices, but they do post prices on a grease board by the Pay Window. If you're not getting Extrusion for them, ask why not. If they won't explain in a manner understandable by you, find another buyer.
