Well, Chuck, I think, in terms of price optimization, we need to look at it in totality. If we're looking at fuel margin for fiscal '20 and beyond, we need to remember there are several elements to our fuel strategy other than just price optimization, which would include the product optimization opportunity, the fleet card strategy, and so forth, that we believe can influence not only gallons but margin. But within the price optimization opportunity, certainly, we should see a more steady balance in terms of the increased gallons quarter-to-quarter, as well as the margin. As you know, historically, you can see some fluctuation in those gallons. If you look back and compare to third quarter last year, a 3.8% increase in same-store gallons for the quarter and the month of January was up 5%. And so what we're looking for is a more balanced approach, if you will, in terms of those gallons as well as the margin. And we're going to look at that on a market by market basis. And in doing so, we're going to understand that not every strategy is going to work in every market. And so we'll take some time to make sure that we understood what those rules are in each market, also knowing that those rules may change depending on the reaction of competitors, not only to our strategy but to other competitors within the markets. So, in short, I would certainly hope that, at some point in time, we're going to find that balance here in the very near future. But at the end of the day, what we're really driving for is gross profit dollars and I think we're starting to see the results of that, certainly, from Q3.
