Every time you make a purchase that charges your credit card, iTunes or Google Play sends you all your purchases receipts directly to the
e-mail address you have registered in your iTunes or Google Play account.
所以，要查看收據的簡單方法就是查看您用來註冊 iTunes 或 Google Play 帳戶的電子郵件收件匣！
If you are unable to find the receipts on your e-mail inbox, you can always check for the receipts directly on iTunes or Google Play.
