What to do with amazon gift card?

I have received an amazon gift card for affiliate commissions for $36, as I'm from the UK I have no idea what I can do with this.

It's not exactly life changing money and I can't buy much with that, I'm not promoting amazon.com now either so I won't get any more.

Is there anything I can actually do with this?

You can buy christmas presents for your family.

You mean business-wise? I can't think of much, why not just treat yourself to a Christmas pressie?

With $36??

I can't see anything being delivered from the US to UK in 5 days!!

No not business related, just looking for suggestions what I can do with it as I have never had a gift card from amazon before.
