Saving 50 cents on a gallon of gas was a big deal to Canadians when the price was at $1.50 a gallon, but not nearly as big a deal when it's at $3 a gallon.

When gas prices go up 5 cents a gallon, that's maybe an extra $10 a week out of consumers' pockets. But when they're going up 15 cents and more, it means $20 extra a week.

When gas is $3 a gallon the retailer is responsible for about 4 percent of the cost, but they are getting 100 percent of the abuse.

It surprised me that it stayed the same today. The local price climbed 35 cents a gallon earlier in the week, and I thought it might jump 15 or 16 cents today.

If the high-grade gas commands 20 cents more per gallon, ... he can pocket $200 for selling 1,000 gallons of regular at the higher price.

When the price of gas goes up, they pay more. When the price of gas goes down, they pay less.
