[Translation from Japanese to English ] You want to purchase the second grindstone, but if you are not sure which one...

Original text

あなたは2個目の砥石を購入したいとのことですが、どれを買うか迷っているなら、
1個目の砥石を先に発送したいと思います。2個目の砥石を購入する場合は、
送料は$9.00でけっこうです。

あなたに販売した剃刀は、中古品で価格も安いので、コンディションは
あまりよくありません。実際に同じタイプの剃刀を使用するのであれば、
$100前後の剃刀をおすすめします。

しかし、あなたは大切な顧客であり、また私から剃刀を買って欲しいので
、$30.00を返金したいと思いますがいかがでしょう?

お返事待ってます

Translation / English

You want to purchase the second grindstone, but if you are not sure which one you want, I would like to send the first one first. You can pay $9.00 to have the second one shipped.

The razor blade your purchased is used and inexpensive, so it is not in good condition. If you would like to use a similar type, I would recommend one that costs about $100.

However, you are an important client, and I would like you to purchase from me again, I will issue a $30 refund. How does that sound?

I look forward to hearing from you.
