Will there be a special price if you buy macOS + Win upgrades?

I currently use Scrivener on a Mac and couple of PCs. If I remember correctly, I had purchased the licenses as a bundle.
Will that be an option for version 3.0?
Instead of buying the Mac upgrade now and the Win one whenever it is released, I would rather wait and buy both as a bundle.
Or even better, I would love to pay for the 3.0 bundle right away and start using the Mac 3.0 version. I can grab the Win version later, and make do with the betas in the meantime.

It’s not possible to get a double discount. You can get the bundle discount, or the upgrade discount, but not both.
