Noticed this too,absolute joke with all the issues this game has.
It's already more expensive for gold/gems then any other game I've seen,the product is inferior to most Apps too.
They should reduce prices rather then increase them,way I see it is they just return to original price or less to be honest,either this or make health/energy refills cost less I.e 10 or 15 gold.
If GREE keep with this pricing policy I will go gold free personally,enough is enough
