This is very odd. I would be a little concerned if they would not allow me to pay in store and take it home from the store, even if it could not be viewed in the store. For such a piece, I would like to examine it for any irregularities before purchasing it, but if you are ok with not seeing it, I would at least request to pay in the store and to pick it up. I would also ask if you need servicing for the piece in the future, can you bring it in to the store? They can’t imagine it will be kept a secret who the piece was offered to, because even if you don’t pick it up (even already boxed up), you will wear it and if other staff really want to know, they can look it up in the computer system (vs checking video from the HJ room, where you can try it on privately). Just trying to think of any rationale they might have, not that I think this is reasonable. Of course, if you get a payment link, make sure it goes to the typical Richemont payment link (or what ever is normal for you locally).
In regards to the particular stipulations you received; I did not ask after the release myself, because a friend was able to buy one piece and not another, and her SA told her the qualifying here and I do not qualify (for lapis/turquoise, lapis/pave), while in the past I did. In our location, currently it is $xxxxxxx spend + x in x category + y in y category, or $xxxxxxxxx spend + x in x category or y in y category. In another continent another person who is buying another piece was told that she would need to buy either a or b and then she could purchase lapis/turquoise or lapis/pave (already with a qualifying purchase history).
All of that to say, that the only stipulations I have heard are that for people who qualify already with their profiles, they are told directly or indirectly that they still need to purchase a or b to get it (since so few will be released, not every strong and diverse profile with HJ and HJ watch purchases will be able to be allocated a piece from the initial release). I have not heard any stipulations on how it can be viewed or picked up, but my sample size for this specific relaunch is only 2 and in only 2 regions.
