The HeraldSun is giving away a free Pedometer with the purchase of the newpaper on Satureday 31th Jan 2008. The offer is only available at newagents (I don't think supermarkets, service stations and the like will apply). Offer is open whilst stocks last.
The picture seems to indicate it is a part of a promotion for the Biggest Loser. Seems like a pretty good deal to me.
Basic details are on the heraldsun web page http://www.news.com.au/heraldsun but it doesn't give much information I'm afraid.
Usually you just grab the 'coupon' out of the herald and bring it in to your newsagency. Make sure you ask about the Pedeometer before you buy because as usual they run on remarkably fast.
