Lonely Planet have a pretty cool competition running at the moment, together with Jetstar, they're giving you the chance to instantly win all sorts of cool stuff.
The main prize is the $10,000 travel card, but there's also 10 $2,500 Jetstar flight vouchers, 50 Nikon Coolpix S3100 cameras, 35 dandy looking suitcases from Catherine Manuell (presumably that means something to someone?) and 250 copies of The Travel Book. All you have to do is purchase any Lonely Planet title, which will have a sticker on the front and the sticker will have a unique 6 digit code that you'll need to enter, along with your details, at www.lonelyplanet.com/jetstartravelcard
UPDATE: The competition ended on the 2nd of September, I hope you won something!
