I think Renato is right on.

It all depends on how fast a sudden price increase occurs.

We could have a 7 to 10 cents a week increase and few people would notice.
Who knows, after a couple of months they could stabilize the price and even roll it back a few pennies before increasing again.

Like the frog in a pan of water.

In fact, they're already doing this and no doubt the price will be at $3.00/g again. $5.00 isn't out of the question, as long as it is incremental.

Efficient drivers do it better.
