A little niche perhaps but after just purchasing a Vault X Binder all the way from the Amazon UK, it looks like Vault X has opened up their own storefront at Amazon AU.
For example, right now they have their Vault X Premium Exo-Tec XL Zip Binders - 12 Pocket XL Trading Card Album Folder - 624 Side Loading Pocket Binder for $55.49. They are available in 4 different colours. I don't really need another binder right now, I haven't really even used the first one but I'll definitely keep an eye on the store to see if they are legit.
As of now, it looks like they only have their Premium Card Binders available for sale.
Thanks, looks like a good place to store all the credit cards I have.
