The 'Plus One Sticker' used to be in the Cash Shop. Since the revamp it seems to have disappeared. Was it retired, or am I just not looking in the right section?

I made a thread last week asking the same thing, but no one seemed to know the answer. Maybe the staff can tell us?

It's not currently in the CS, no. I believe it was removed around the time we got the ability to offer CSC directly on trades, but I can't find when that happened to confirm it.

The sticker is super cheap in user shops (worth far less than the value of 1 CSC) and there's an alternative to get rid of uneven amounts of CSC now, so the sticker isn't super necessary to have anymore

My belief matches that of but like her my google-fu has failed me and I can't find a source for my odd thought about the sticker either. This is why I didn't respond earlier.
