I'm hoping someone can provide some insight. I've perused the site digimart and there's an amp that's caught my eye. Issue is, I can't read/speak any Japanese. I know the digimart site is just an aggregate of different shops in terms of what they have. I've tried thinking of registering on the site, but can't understand a thing.

Also, are prices firm or do people negotiate prices in Japan? I know some countries culturally do/don't negotiate on prices.

Thanks.
