Uhhh, yeah, this is new material we have just processed. I'm getting the leftover stuff, all nice & shiny. When I dropped off that 1st batch a couple weeks ago, I only had 300#. (And I think their truck scale was off on the high side.) I don't know if amounts effect what they give you. This yard is only 20 min away, though, and in the future I'll be bringing more weight at once.
