Gas stations in Montreal still do the "let's ALL raise our prices by 5 to 10 cents all at once, followed by lowering verrrry slooowly over the next week!" thing, usually starting on a Thursday. However, the jumps are no longer absolutely guaranteed every week and the jump-lower cycle has been coming down from the stratosphere.
The last price I saw was about $1.299 at pumps near my house. Costco is probably 5 cents cheaper.
My hope is to see $1.199 by the end of November. Lower still would be asking for too much, methinks.
