Sorry for the error. The prices should be up in the next two hours.
(しかも2時間以上経っても全然変わってないし)
待ってる間、naaも価格調整してくれるのかな~と調べてみたら、こんなでした。
■The price reduction must qualify for an adjustment. This means the price reduction cannot be a "date specific" event (IE: prices valid from 11/11 - 11/18) or state "no adjustments on prior purchases." ■If the reduction qualifies, the request must be made within 7 days of the original order date.
