It's always nice to know where the best deal is before gassing up. Well thanks to GasBuddy.com, you can. The site shows the best (and worst) gas prices in almost every city in North America—including Peterborough.
Also, if you have an iPhone and fill up at Petro-Canada, don't forget to check out their free app. It gives you directions to the nearest Petro-Canada gas station and tells you the current price per litre.
