I keep my mini-map open so when I see a crowd of AVs grouped together I know it’s either an orgy or a sale/event…and in this case, I got lucky and it’s a sale/event.

The VIP group is free but the small print on the poster says that at the end of the month it changes back to a paid group and you also have till the 30th to spend the credits.
The picture is of the poster in the shop and you click it, to find it and the wall of group gifts and lucky boards just head into the back room.
PS. It’s busy.
UPDATE: My “PS” turned out to be prophetic as the sim is down. They’re probably just doing a restart as it was packed when I was there.
(I’ve amended the LM if it doesn’t take you to the Trend shop it means you’re next door lol. Either open your mini map and follow the crowd or leave the shop and turn right and go through the neon light tunnel…easy to see).
