I was at the Costco in Everett, Wa today and they had the Hammerhead sleds in stock for $79.99. They seem like a quality sled. I might be asking Santa for one.
I didn't see the Hammerhead Sleds in the Arlington/Smokey Point Costco, so I asked about them at Customer service. I was told there were none on order, but Everett, Burlington, and Bellingham Costco all had the sleds in stock. The Hammerhead sleds were sold on Costco's website a couple years ago, so we might see them offered online again this year.
