It might be getting near the end of summer, but "getting near the end of" still means it's summer. That means there's still time for summer sales. West Wind Productions has theirs going. So go pick up some minis for the upcoming winter for cheaper than you'd usually have to spend.
Whether you want some WWII minis or some Arthurian ones, West Wind has you covered. Just enter the appropriate code at checkout and they'll get you your discount. If you're not interested in either of those, you're not out in the cold. They also have an Overstock sale going on. Various items have been discounted 30%. You can go check those out, too.
