It's Shari. A few comments. One, first in terms of the question around labor, we have already done work and will continue to do it around pulling out nonproductive, non customer-facing, tasking and operating tasks labor, and the team did a very good job of that at the very beginning of this year that we then turned around and reinvested into gaming categories specific labor. So we funded the gaming value proposition and dedicated labor by taking unproductive labor out of other places in the store. That's always the first choice, and we'll keep doing that. Secondarily, to your question about training, yes, we absolutely have to be better in what we're delivering to the customer and the level of knowledge, selling interaction and skills that we deliver in our stores. We've got a, I think, good legacy of being very good at that. And given who our competitors are today and given what the demands are of the customers, we have to be better. And to that, we put a significant investment in training across all of our stores, specifically focused on both the product knowledge side of it, as well as the selling skills side of it. And we're in process of doing that right now. And then thirdly, in terms of op model changes, we've talked before about some of the things we're testing in the Connected Stores, of which we now have about 30 plus stores operating with that operating model. And yes, we found that in particular in the spaces where there's more complexity for the consumers. Mobile is a good example that you already know about. Computing is another example of that, where we get the right level of dedicated labor to that, and we've got them in both a different compensation model that includes compensation around their overall productivity, as well as how their customers rate them, as well as their demonstrated level of knowledge. We like the early results we're seeing there. In fact, in our test stores, we now have the 2 tiers of different selling skills and selling roles in the store. And it's still early but we like what we’re seeing so far. So yes would be the answer to number 3. And as always, we just got to make sure that we get the return that we need on the changes. But there's no doubt there's opportunity there.
