I did have one bad experience with Amazon - after my Border's gift card couldn't get through, I had to order through its customer service. Though they knew my billing address in Indiana, they still shipped it to my old address in Arizona. It was their fault for not even ask me where to send the package. They refused to send another package until that one arrived - so I had to place another order and paid first.
I have been ordering from Amazon - their price was pretty good - almost 30% difference than if I drive to Border or Barnes and Nobles. I know I had a bad experience this time - but hopefully I'll have a better luck next time.
In conclusion - nobody is perfect - learn to live with more flexibility will make you a happier person. Besides - I think it's your fault to order gift card that late. In my case, I need the books for my class that starts in 2 weeks - I have plenty of time to rectify the situation rather than bashing the company.
