One approach would be to save up for your Christina Aguilera concert ticket. That's an approach, but it's pretty dull! Another idea would be to try and sell items you no longer need on eBay. You will certainly make money from eBay, but what a bore! Or you could fall on your knees and ask the person who you think would be most susceptible to your hard luck story. Maybe they could play the merciful role and pay for your concert ticket?

If you're not persuaded by these relatively sensible ideas, you could entertain more unusual suggestions in raising the money to purchase that ticket?
