summer break gives 1300 power? Since it costs more than double of youth sai...

The price is not more or less always like this. For all the other costumes, price starts at 100 a frag for a couple events, then drops to about 50 a frag after it's been out for a while. Summer break cost around 200+ a frag when it first came out, and was only in lucky star once I think for about 100 a frag. I'm just not sure if summer break costs more and that was the reduction, or it cost extra during that first event, and it will reduce to about 50 like everything else
