1. Internet
Some websites post real-time gas prices. You may find the cheapest gas price
around your region on the web:
GasBuddy.com
GasPriceWatch.com
2. Cell Phone
If you send your zip code (postal code) to some companies, they will notify you
the cheapest gas price in your region by text message.
For example,
gas@gasbuddy.com or
sms@mobgas.com can send you real time gas prices.
The service is free if your cell phone plan covers text messaging.

poor regions are relatively lower.

7. The gas prices are more expensive at gas stations who provide maintenance service.
8. If you use Shell Mosaik MasterCard, you may get up to 5% cash back and other
discounts at Shell gas stations in Canada (annual fee is needed).

MasterCard. You also collect Petro-Points. (no annual fee)
