Buying in Australia: Forgotten Realms Ultimate Bundle

Hi,

I'd like to buy the physical and digital Faerun bundle for myself in a way that is compatible with DnDBeyond. It's where we currently stage our campaign, which is mostly set in Sembia.

So far I haven't found a way to do it. Which annoys me. My players and I rely on DnDBeyond's VTT but it's super expensive to buy the content on if you are not in the USA.

Has anyone else in Oz worked out a way to purchase the bundle and have the digital content available in DnDBeyond's VTT?

Alternatively, I'd be open to hearing about good alternatives to DnDBeyond. I've played a couple of them but haven't DMed on them.
