This is a set that they had as part of their seasonal items. It is now marked down from $149 to $79 in many stores.
Some stores are out of stock already, so YMMV.
I was able to order online for a store and have it delivered via free delivery. "Truck Delivery" is expensive as always, so you will have to either pick up in store or find a store with remaining stock and the "Ship to Home" Option.
These stores appear to still have inventory and offer ship to home:
