Visa Gift-Card Question

Ok so I have a non-reloadable Visa debit card I picked up at target. I have this card has my only payment method when purchasing on amazon with a zero gift-card balance. I spent the $25 on the card. A few days ago I accidently clicked "1 click purchasing" on an item I was viewing. I didn't think much of it assuming that since there was nothing left in my card, the transaction wouldn't go through. Today I checked my email and to my surprise I had an email confirmation about my order. I'm positive there was nothing more than a $1 remaining on the card, so how did a transaction of $20 go through? I went to cancel the item, but it shipped already so it's impossible for me to cancel. I'm afraid I did something illegal and I'm not sure what to do. Help?

This card is not linked to any bank account or paypal btw.

 

Dont pick it up they'll return it. I forgot to pick up my speakers and they got returned to the seller and I got refunded.

 

It anything, they took more from your account. If you didn't give info, you probably give it without knowing

 

Usually theres a number on the back on giftcards for balance inquiry's. If there is one, call them and find out how much is actually on the card.

 

yeah i wouldnt take it unless u want to pay for it later lol

 

You can always ring up PayPal, and explain that problem or the website you ordered it from (Ebay/Amazon i'm guessing) - There's a few ways around it, but also as Roary said, when it comes just don't accept it, that way it can either be sent back to the place it came from, or it will stay at the post office till further notice.

 

thats what i do
