##環境：
firefox
mozilla geckodriver(https://github.com/mozilla/geckodriver/releases)
python3.x, Mac
##使い方:
13-14行目：
amazonPassword="password"```
を個人のアカウントとパスワードに差し替え。
118行目：```years = range(2009, 2020)```  ← 抽出したい年範囲に

##outputエクセル：
A列：注文番号
C列：購入当時実際に支払った金額（送料など込み）
E列(checkPrice、送料別途)＝D列明細内の各商品単価＊数量
E列とC列合致しない場合、下記の原因が考えられる：
・送料込みか別途発生する
・商品単価の変動
