Bump, expires today! 
I just deleted my initial post after reading this but then I read your OP.
As far as I know Amazon gift cards don't expire and if they do, they only expire after years of inactivity. I've had lots of gift cards lying around for months before being redeemed.
In your OP it says that Te voucher expires on Sun Jul 13 2025.
Firstly, today is Monday the 13th of July and secondly, it's only 2015. I'd say the card has another 9 years and 364 days left before it expires. No need to rush into selling it
Woah, well now I feel embarrassed... I guess you are right
I didn't look closely enough, only saw the day... As I said, never used an Amazon gift card, don't really know the ins and outs about them. Still selling tho if anyone wants!
