I’m very fortunate that I don’t drive many miles per year, I think my truck just turned 12k miles and it’s a little over a year old, however, like anyone I’m not very pleased about paying $60 to fill it up (shit, I paid $20 to fill up my motorcycle in Death Valley on Friday, but when you are staring down 100 miles of nothing but desert you really don’t complain that much). GasPriceWatch is an interesting service because it can identify the lowest price gasoline based on your address or zip code. They even have a Dashboard Widget, but the mobile service is still in development and that is arguably the piece that is really needed.

These services, and there are others, all rely on community involvement, anyone can register as a spotter and send in updates.
