Query: Worked Great... While it WORKED :(

I bought this curling iron in February 2008. It is now October 2008, and it has just stopped working. I only used it 2-3 days a week, never dropped it, or got it wet. One day, it just stopped heating up :( Before that, it worked GREAT! It's hard to find a 2 inch barrel curling iron... Unfortunately, it has been longer than 30 days, so now I can't return it, and it can't be exchanged because it is no longer available.
