Yukata in Winter

I'll be going to Japan in wintertime, and I gather from this site that the places that would be selling the most yukata then in Tokyo would be the Uniqlo at Narita or the Oriental Bazaar on Harajuku? Does anyone have an idea of what the prices at the Oriental Bazaar for yukata are like?

Yukata are also available year round at Nakamise Shopping Street in front of Sensoji temple in Asakusa:

Yukata are not sold at Uniqlo in the winter- I visit Uniqlo stores about twice a
month and can say 100% that they don't stock yukata until late spring.

The stalls/ stores on Nakamise dori and Harajuku are aimed at tourists so they do seem to carry them year round.
