Amazon購入履歴のCSVエクスポート (2017 年バージョン)
// Amazon購入履歴のCSVエクスポート
//
// 使い方:
// 1. 全部コピーする (右上の Raw をクリックした先でやるのが楽)
// 2. Amazon の注文履歴ページ ( https://www.amazon.co.jp/gp/css/order-history/ ) を開く
// 3. F12 または 右クリ→要素の検証 とかで出てくる開発者ツールのコンソール (JavaScript REPL) にペースト
// 4. エンターで実行
// (Firefox はなんか allow pasting とタイプしろみたいなことを言われるので従う)
// 5. しばらく待つと、コンソールに合計金額が表示され、CSVが保存される
//
// 2014-12-28 / 2016-05-10 時点での DOM 構造に対応, Firefox と Chrome でテスト済
// 2017-02-18 CSV保存機能の追加

There's a chrome extension doing similar thing,
https://chrome.google.com/webstore/detail/%E3%82%A2%E3%83%9E%E3%82%BE%E3%83%B3%E6%B3%A8%E6%96%87%E5%B1%A5%E6%AD%B4%E3%83%95%E3%82%A3%E3%83%AB%E3%82%BF/jaikhcpoplnhinlglnkmihfdlbamhgig

but seems they are suffering from the same problem now. (it appears that Amazon has changed the page layout last Dec).
The developer of this extension is aware of the problem and hopefully they will fix it in near future.

FYI, Amazon Business has official support for exporting purchase history and invoices.

Great! Thanks a lot for your hint. 👍
I will check from time to time if new version is available which support current Amazon.jp page layout :-).
