一挙両得 アンド 一石二鳥

[stevesayskanpai]

Just studying Yojijukugo 6, and couldn't find an explanation of the differences between 一挙両得　アンド　一石二鳥。

手伝えますか？ Can anyone help?

It's just 2 expressions that have the same meaning in the end.

1 action, 2 gains
vs
1 stone, 2 birds

One is more literal and one is more figurative.
