セールの案内をメールでもらったので、いくつか商品を購入したいのですが、
クーポンコードを使っても20%OFFになりません。

Hello.
As you have emailed me notices regarding the sales, I would like to buy some items.
I was unable to enjoy a 20 % off even if I use the coupon code.
Are there any conditions for the discount?

Hello,
I would like to purchase some of the merchandise since I received an email about the sale, but they were not discounted by 20% off even I used the coupon code.
Is there any conditions to use it?
