Joe, well, we've got a plan, we've got a road map that sort of -- we're not doing everything at one time, some things have to be done before you can do the next step, by the way, but we have a plan for that for over the next 3 years, of systems integration. We're doing a lot of work around what -- bringing together shared services as a priority, being able to, for example, get everyone on the same financial system so that we can pay all the bills the same way using the same system. We're currently, you've heard me reference St. George, Utah. We're currently working on combining and integrating the WMS systems. We're taking a Family Dollar bannered DC in Saint George, Utah, and we're doing that right now. We'll start receiving some time April, May, the Dollar Tree merchandise along with the Family Dollar merchandise, and we'll start shipping and testing that shortly after that is the plan. And of course, when we get that right and we have confidence that we can do that other places, then we'll begin rolling out and combining some others, DCs as appropriate, to do 2 things. One is to give us more capacity in the buildings that we own, whether it's Family Dollar that needs the capacity or Dollar Tree that needs the capacity, by being able to ship both banners out of any building will enable us to use the capacity better. And secondly, to improve the cost structure by rationalizing the DC network, getting the DCs in the right places to serve the right banner. So that's some of the priorities that we have. We're going to keep the merchandising separate. There's some of the back office things to do with merchandising we'll try to leverage, but Family Dollar buyers are going to be buying using Family Dollar systems and Dollar Tree alike, using the Dollar Tree systems, as far as retail purchasing right now. We're going to combine some of the back office things and leverage our international sourcing, leveraging freights across both banners, leveraging our international organization across both banners, our QA, QC, all of those things we'll be leveraging. So that sort of gives you a color. There is a road map for the entire network, system by system, and it spans the next 3 years, with the most important things to get -- to glean the most value the earliest at the front end.
