Perhaps this post is a bit premature. I visited Nagoya BITS card shop on my first trip to Nagoya about a month ago, and I picked up a few oddballs I saw. But I'll be returning in a couple weeks when I go back to Nagoya, so I'll have an even better look at the store.
As I said, I'll be back at the store in a couple weeks to get a better idea of what's available. I recall the store having all the regular products, but I'll pay better attention next time when I have more time to explore.
