, What is the site used for the graph posted above?
One of the many options under GasBuddy mentioned in post 8. (Price Charts)
Interestingly, there was one place in Barrie at $0.829 this morning, but now it's over $1. I don't try to save every penny and don't buy "off brands" but if I'm less than half full and see a good price, I'll pull in if it's not busy. If I'm going on a trip and need gas on the way, I'll also usually do a quick check of the route before leaving. Since we're retired, our "local" needs are less than once a month.
