Yes. Thanks, Simeon. So yes, I mean, when you talk about PPI, that's over 2 years old now. Basically, we're lapping at 24 months in. We feel extremely good about that investment we made. When you look at those categories, not only those categories, but kind of the halo categories that revolve around those [indiscernible] underhood categories, and it was very broad. It was a very [indiscernible] approach, but it was very broad by SKU, by line. We feel really good about what we've done there. We -- when I look at it, especially versus some of the WDs and the independent 2 separate type players, we feel really good about what we've done, and we haven't seen really any other reactions to any large degree out of our big competitors nor those other competitors. The reason that I feel like that we have made those investments pay, Simeon, is because our team has gotten out there and this just hasn't been a one-pronged approach.
The investments were one thing, but we knew going into it, the only way we were going to make that pay was to do what we already did well even better, being out there calling on customers, building relationships with those customers that had traditionally bought from some of the independents through relationships, through service, et cetera, and some of that being price. Our teams have got out there and done all the other things that matter more than pricing, calling on customers, building relationships, the most efficient delivery service in the aftermarket, right part, right place, right time, the work our supply chain teams have done in the last couple of years have all made that pay off.
But really to the last part of your question, we feel really good about where our pricing matrix is. We moved it down to that level that you know we did on the professional side, but we're always within that new matrix. We're always tweaking and optimizing within that new matrix. But we feel like that matrix is where it needs to be for now in the foreseeable future and don't see anything competitively that would tell us we need to ever do that again.
