weirdness in unicycle marketing

a friend needs a rail adapter and we were looking and saw that the KH rail adapter with brake mount goes for $69 on uni.com and 35 ($29 us) on Bedford?

at that price we could buy them and make a profit selling them, i dont get it. did i miss somthing here?

i also need a KH Fusion Seat and was surprised to find that uni.com only sells the cover. the only way to get the Fusion seat from uni.com is to buy the whole uni. Bedford has then at $55 ca.

???

Licensing agreements to the retailers from KH I bet.
(just a guess)
