Not sure if this is an error, but this set ($ 799.99 new) is showing under the category of used but you can select "new" for less than their used price. There is also a 20% off used Cobra Clubs promotion "TAKE20" that takes these down to $ 431.99, and "SHIP99" gives free basic shipping.

Killer deal if they come brand new as stated. If not, they accept returns and pay shipping if it is a result of their error. I took plenty of screenshots prior to ordering.
