日前（8/16）所下的單子寄出之後
昨天赫然發現阿甘pre-order時只有25％ off
現在去AMAZON買反而有30％ off
一時不爽寫信去罵
結果如下
Thank you for writing to Amazon.com.

The discounts we offer for items on our web site do vary from time to
time. I've checked your order, and found that we now offe a greater
discount on Forrest Gump than at the time you placed your order.

Please accept our sincere apologies for any inconvenience or concern this
price change may have caused. Since this item was shipped so recently, I
have requested a refund of $4.00 to your credit card. This amount
reflects the difference between the price you were charged and the
discounted price. The refund should appear as a credit on your next
billing statement.

I hope this solution is satisfactory. Thank you for shopping at
Amazon.com--we hope to see you again soon.

這次經驗給大家做個參考 不要讓自己的權益睡著！
說實在的 Amazon的客服真不是蓋的
