Yes, Steve, that's a fair question. I can tell you that the 2 things that Kevin mentioned, there are things that we do in the normal course of business. We have doubled down on our testing, testing more times, especially on some of the categories that are more subject to compliance issues. And the idea is we don't want to fail. We want to make sure that we're providing the safe product for our customers and we doubled down on our testing. I think that's a onetime, not that we're not going to continue testing, but what you saw there was a little bit of a bubble based on a change in the way we are doing our testing that will smooth out over time. I have great confidence we'll be able to manage that for the long haul. The second thing was the big -- largest impact was our DC productivity was lower in third quarter. And there's a couple of things there. And they're all -- you can point to them, we can identify them, and we can fix them over time, but we are here at peak inventory times at Dollar Tree. We are receiving all the products for -- in the third quarter for our third quarter as well as our fourth quarter sales. It was a peak inventory time. And at the same time, we decided to rebanner a couple of hundred Family Dollar stores to Dollar Tree, and we've scrambled around to buy the product and insert that into the inventory equation, receiving it in the appropriate DCs and maybe signing things a little differently, moving things around, as well as rebannering our Deals stores, which, over time, we're not going to start that until January. But just the planning and getting things positioned for that reduced our overall productivity at a time when our buildings are at absolutely maxed peak capacity. As I mentioned a couple of times, we are building a new distribution center of 1,500,000 square feet. We always build ahead of the need, but just ahead of the need in South Carolina to serve Mid-Atlantic and Southeastern Dollar Tree stores as well as expanding our Stockton distribution center over 50% for next year. So we're opening up more capacity while we're doing a lot of things in addition to what we'd originally planned in our distribution model. The result was we had some distribution productivity lag. At the same time, our outbound transportation, which is something we've talked about before, was also a little higher than it has been in the past. So all in all, things are identifiable opportunity to improve, and we will improve on those. But that was really the main components of the drag on the gross profit number in the third quarter.
