商品説明に、賞味期限が04/2011が2箱、01/2011が１箱、03/2010が2箱で、合計5箱の商品と記載ありましたが、実際届いたのは04/2011が１箱、04/2010が1箱、01/2011が１箱、03/2010が2箱でした。
賞味期限04/2011までの商品が1箱、04/2010の商品と間違えて送られてきたようです。
交換して欲しいです。間違えて入っていた商品のLOT番号は CS１００８１です。
LOT 番号CS09891が2箱送られてくるはずが1箱でした。

Translation / English

In the item description it was recorded that the expiration date was 04/2011 for 2 boxes, 01/2011 for one box, 03/2010 for 2 boxes for a total of 5. However, the actual number received was one box for 04/2011, one box for 04/2010, 1 box for 01/2011 and two boxes for 03/2010.
It seems that one box of the 04/2011 and one box of the 04/2010 were sent by mistake.
I would like to replace them. The mistakenly sent products' lot number is CS10081.
As for lot number CS09891 two boxes were received, we should have received only one.

Translation / English

The explanation said there are total of five boxes which expiration dates were, for two of them were 04/2011, another two boxes were 03/2010 and the last box was 01/2011, but what I actually received were one 04/2011, one 04/2010, one 01/2011 and two 03/2011.
The box with expiration date 04/2010 was shipped by mistake in a place for the box with expiration date 04/2011. I'd like to request an exchange. The LOT number for the box sent by a mistake was CS10081.
I was supposed to receive two of CS09891 but I only received one.
