Huh? ⇒

Have any of you noticed what Vancouver gas stations are doing now? I have seen this behaviour in Abbotsford, but I don't understand it.

The advertised price is say 91¢ a litre. But then there is a sign on the ground that says, "Save 3.5¢/litre at the pump"!

Why don't they just lower their prices by 3.5¢?

I just don't understand it. Am I missing something?
