你買卡的時候，店員可能沒有正確scan，那個scan是activate

有個和你一樣的例子

As a follow up, we found out that the gift card was not activated. Either the cashier at the Target store it was purchased at did not activate it, or there was some failure in the activation once the card was scanned for activation. Target refunded the amount of the gift card purchase to the purchaser using their debit card without the receipt. 

這個聽起來是對的，禮品卡不是商品，我記起以前看見有小孩挑好看的卡拿走，都是不能當錢用的。
