I guess I'd just add that conversion is not a fine-tuning knob, it's a gross-tuning knob. And conversion rate is a function, first and foremost, of the attractiveness of our merchandise assortments. Secondly, it's a function of our in-stock position. Thirdly, it's a function of the quality of the customer experience inside the store. So there's a whole lot going on. Having said that, for example on size optimization, about half of our product, say 40% of our product, we order and we never order it again, okay? It -- because we're a fashion business. It's fast turn, it's in and it's out. There's another 10% of our product that we order that is opportunistic buys or closeouts. And we don't order that by size, we get it in the way we get it because it's opportunistic. So the other 50% is product that we order and then we either replenish it once or twice or indefinitely. And it's that half of our assortment that is really benefiting from the systems initiatives, particularly size optimization. So when I slice it a little further and I look at the items within that 50% that are replenishment, that's probably, I don't know, 35%. And then if I take core items, which are items within replenishment that are going to live for 6 months, that's probably more like 25% or 30%, okay? So on those items, those core items that are going to be most impacted by size optimization because we're going to buy back into them by size and allocate them precisely by size and we're going to buy them in solids and not in musicals, our in-stock rate in Q2 was up about 7%. So -- and we know what the sell-through rates associated with various in-stock levels are so we can project what the sales impact was and it was meaningful. So I hope that gives you some additional flavor as to how we're looking at and evaluating the impact of systems. But in terms of translating that to a specific impact on conversion, that's dicey.
Seth Sigman - Crédit Suisse AG, Research Division: No, that's very helpful and it's certainly an encouraging trend. I just want to follow up: Doug, a question on the SG&A. Really good control this quarter and I'm just wondering, that low-single-digit growth that we saw in terms of dollars, is that kind of a sustainable level? Like, what are some of the moving pieces we should be thinking about for the rest of the year?
