Umm the eastern shop itself is good enough. It's like the secure option for people like me who planning to buy sakura. If I can't get myself a 30% discounted (2k8) sakura in treasure of the asge I'll buy her in eastern shop for 20% discounted. (3k2).
How about stop whining about something not worth the try at all? Like really? Nothing big deal here, it's not like they added more recharge events as additional event like what they did last time. This is actually a good event.
