its more of this: if you buy stuff in myshop, you get rewarded with talk time.
(you still need points to participate though)
I wish it were free Q Q
(or at least one talk per day?)
curious note: when you buy a lol box, you also get a ticket. if you gather enough tickets, you can trade for the lol box's pet. (its probably for those who are REALLY bad at getting pets from lol boxes xD)
