costume summon event

With this costume summon event i was happy to try to summon for some costumes i wanted and get some more from boutique coupins but when i go there i see they increased cost from 12 coupons to 50 frickin tickets i had 15 before and could buy one but i was waiting for some new costumes to be added

If i knew they would pull this shit i would have spent and bought a costume but now as it costs 50 coupons i cant buy anything
