Yeah, between chatting and the card game, you can collect a nice little stash of tokens to get things with. Plus, the outfits in the Event Shop are at their cheapest. Other than the Event items, everything else will become a regular item after the event is over, but they'll cost twice as much. Some people also use that as an opportunity to make money. They buy things now and after the event is over, they sell the items back to the shops to make a profit. I never do that. I'm too much of a hoarder >_>
