Lab maps... ive made prolly 500k off them hahahaha, people price them like they are the petpet ones so many times
The only thing I ever used the Usershop AB for was Shooting Star Muffins... I made over 1 mil off of those things by noon! Everyone was pricing them at 1-25 nps because they were on the Advent Calendar and I sold them for 4.5k each
I remember it was really late at night when someone figured out how to get the snorkle snout avy and I saw the board right away. I bought 100 or so at about 2k and they sold for 95k each, I was frozen shortly after though. Lolz.
