Home Depot [homedepot.com]
Found this deal at my local Home Depot in Central Colorado. This is last year's 40v mower with the 5Ah battery, but the price was right. Brickseek [brickseek.com]
shows it as being on clearance and doesn't show my local store, but there were 4 on display (all were built and just in the middle of the store). Home Depot's website shows it as not available for shipping or store pickup, but you may find some at your local store.
