As a customer of RarezHut, I'd say that this is a great way to purchase Japanese CDs whether you're looking for visual-kei in general or something else, great pricing and it'd be hard to beat the shipping deals they provide. I recently received a rather large order from Val and Panda today and it was safely packaged and in wonderful condition. You can't really beat getting great deals on rare or sometimes out of print CDs, especially with bundles.
Since they also have streaming events, that makes a great way to see all the type of rare items they have that date from the '90s-present. You may even find something that you've been searching for but it's overpriced but that's where RarezHut comes in, great prices and they treat their customers well.
These are just a few of things I've bought from them / here and here
