It will not allow me to adjust the shipping as it goes through a third party. If you want to cancel the order you can. If not a have a few Windsor mats I will give you free also. Let me know.

If buying 8 and getting 10 is better let me know as they come 10 to a case.

配送は第三者が行うので、私には手を加えることができません。もし、ご注文をキャンセルなさりたいならできます。Windsorマットが少し足りない（？）ならただで差し上げますので、おっしゃってください。

８個分の代金で１０個お送りしたほうがいいでしょうか？一ケース１０個入りなので。
