When I bought my 18 WSM in late 2009, the store (Ace Hdwe) had the previous version on display. I pointed that out to them and asked what they could do price wise on it. The clerk spoke with the manager and they said they could come down from $300 to $250. I pointed out it was an older model and had some dents and scratches. They held firm.
I said OK, I'll take a new one then. But they didn't have one in stock.
Anyway, point is they may have some pretty old units on display.
