These are new since I left .-. Uhm.. I guess now you have to be invited? Are they rare?

They are like random events. Just do lots of different things on the site--visit pages, do some quests, games, etc.--and the invite will show up . I usually get an invite every one or two weeks; wish it could be more frequent, but at least this means they're not super rare ^_^

Well.. I know? :') I have two of them just from today. Im sorry, I think I was unclear. I'm not using Subeta anymore and it's of no use to me, I'll be giving them away with the rest of my stuff. My question is: Does it just let you shop at the Subeautique? Do you just show it once and you're in? Or do you have to show a new one every month? Idk. Since Im not playing anymore this is a purely curiosity based line of inquiry

Ah I misread your question ^_^; Well after you redeem the invite, you can go into the shop a million times if you want, just once you buy something that invite is gone.

Ohhhh!! That makes SO much more sense! Thank you! :> I saw them on everyones WL and thought "but I found two today! How can they be in demand so much if you show it once to get in forever?" Thank you!
