What to buy for $7?

It appeared to be a hard question if you have an American Express card with $7 balance.

Actually the creation of this blog and the website was because of this yellow (gold?) AmEx card. I got the card by mail with a "Thank you" letter from one of my partners. On the card there was a usual card number, words "Thank you" in the place where there is usually the cardholder's name and the words "American Express rewards card". From the fine print on the back of the card I found out I was presented with $25. It was nice and it was fun.

The only problem I had now was how and where to spend the given money. Not many shops in my city accept AmEx. I browsed online shops and did not find anything interesting that I could buy for $25 including shipping and handling. Finally I found out I could buy myself a domain name, so I went and bought gershtein.net and opened my web page and this blog. I spent $18 for that.

Now I still have $7 left on my card. Anyone has any suggestions how can I spend them?
