I've been away for a while and recently come back to the site, so I'm not sure how some of the new things work. What's it like when you use a Subeautique Invitation ? Can you come to the shop just once per ticket and if you don't like what's stocked you're out of luck, or can you visit multiple times until you see something you like and buy it?

One redeemed invitation lets you buy one thing from the shop. You can visit the shop as much as you like, the ticket only gets used up once you buy something. However, if you don't have any tickets redeemed, you won't be allowed to look at what's in stock.

Oh I see, thanks! I was worried that I might use an invitation, and then be out of luck if there was nothing in stock when I got there.
