I suspect this is Yukon Outfitters making the same exact hammock under a different brand specifically for Woot. Just like buying the generic cereal in the grocery store under their brand name - the grocery store doesn’t own a cereal production facility, but the producer will make it for less (or in this case, the same) under the store’s name in order to not dilute their brand name.
I would not be surprised to see more Twisted Root Design outdoor gear on Woot in the near future.
