I agree they are burying the hell out of it, but as it stands licenses for 1Password 7 (which is still in beta on Mac & Windows) can only be purchased from within the client, as they want to test the order flow which was rebuilt in this version.

The Windows version of 1Password 7 still can’t be licensed, they haven’t built that part yet. The Mac version however can be purchased, and if you plan on sticking with it I would do so now, as the price will be much higher in the near future. Right now it’s being offered at 50% off.
