I bought two of these yesterday for $269.10 each pretax using 10% Lowes coupon. Got this deal from the Home Depot #6966 in Sacramento, CA. Also, the HD stores in Rancho Cordova and Woodland were out of stock according to the inventory checker, but when I stopped by they both had one in stock. So, if it shows out of stock it's possible they might have one still available. B&M only - YMMV.
