Fukuoka Book-Offs, Hard-Offs, etc.

I only have a day and half to travel in Fukuoka. I'm looking for Pokemon cards, retro Nintendo gaming and need to pick up some plushies and Nintendo Switch 1.

My previous experience in Tokyo, Kyoto and Osaka, was to venture out of the main areas to and the Book-Offs, Hard-Offs, etc. had cheaper prices.

Since time is limited, should I focus on just hitting up all the stores within general radius of Fukuoka or s it worth to travel out to Saga, Kumamoto or Kitakyushu to check out their Book-Offs, Hard-Offs, etc.?
