These have been pretty popular in the past and in particular, the K1 (single person) seems to be the lowest it has ever been at $78+shipping. Thanks to Webluce for pointing out that the K1 is eligible for click and collect from Target and has free shipping with Club Catch.
The K2 (2 people) is also close to its all time low. Shipping for the K2 was $22.95 to Sydney.
Seems like a great deal for someone wanting to try it out. In the comments below, a few posters have also suggested getting BCF to price match.
