Dumped trolleys make your neighbourhood ugly and cost supermarkets a fortune, which gives them another excuse to jack up prices. The Woolworths Trolley Tracker service lets you report dumped trolleys, and uses GPS data from your phone to accurately pinpoint their location.Submissions of rogue Woolworths and Big W trolleys to the service go in a monthly draw for a $1000 prize, so there's a wealth-enhancing incentive as well as a street-cleaning one.
Woolworths says the service works on iPhone and Android devices, and should be available on any GPS-equipped mobile via the sign-up link below. I signed up fine on my BlackBerry, but haven't found a trolley to report yet. If you try it out, tell us how it goes in the comments.
