Perhaps there could be a retailer in Europe that resells Pianoteq? In the US there is Sweetwater, off the top of my head.

Thanks for thinking along, appreciate it! Couldn't find any, especially not with the black friday discount.
In the end I shared my login details in the draw names app, and created a gmail filter that automatically forwards e-mails with the word Modartt, and that archives them. Tested it: my wife receives the modartt e-mail, and I see nothing.

Still, recommendation to Modartt would be: make it easier to gift an instrument pack

So I wanted to make an idiot-proof step-by-step guide for the other person, so he/she can order it for me, but I didn't come far:

As soon as I try to add an instrument pack to my shopping cart, it asks me to login.

I know there is a 'buy as gift' checkbox on the second page of the ordering process, but before you get there, you have to add it to your shopping cart.

Kind of confused, since previous year, it was no problem. Anyone can help make an instruction on how to order it? Thanks in advance!

P.S. The best I came up with myself is: share my credentials and let the other person buy it on my account. On my e-mail I would make a filter, that would automatically make mails containing modartt, pianoteq or the name of the instrument pack invisible.
