As of right now these are only sold for retail at Home Depot. I have noticed that many HD stores are sold out when you try to do an in store pickup. List price is $79.98 each. They are already listed on Amazon for $139.00. I except these numbers to go up in late November. If not HD offers a 90 day return policy. So if you can spare some cash up front you might want to take a shot on these.
As always do your own research before making a decision.
