All right. Well yes, I'll talk about the overall competitive environment and what we're seeing in there, and then Paula can give you some more color on the merch margin and our outlook related to that. So to reiterate, as we look at the competitive environment, what we, as I mentioned in the remarks, this category has always been an attractive, and it's always been very competitive, given the growth potential, the connection it has with consumers, its margin profile. So we've long, for the entire 33-year history of this company, we've been competing in a very competitive environment. What's unique about what’s going on today, is the cumulative impact of the competitive intensity really driven by significant increase in distribution of prestige, both in store and online. And as consumers navigate that broader choice, they're making choices. We're confident in our ability to continue to engage, and that shows up in some of the results I highlighted, but it certainly is an impact. When we look at stores opening near our stores, we talked about this in the past, historically. We do see a short-term hit to a nearby store when a competitor opens up and we're able to recover and those stores comp at our enterprise level. What's unique about right now is the scale of it to have over 1,000 new locations within a short-term period. It's unprecedented in our history and probably in retail more broadly. So it means that we're navigating that and understanding consumer behavior as we go forward. But even with that, to highlight again some of the things that we see, our strengths even in this elevated competitive environment, holding share in total beauty for the quarter is a real positive as we gained in mass and we gained in prestige e-com, in our brand love, our brand awareness, our total loyalty members, our member retention, our traffic all up, all positive, all healthy, as we see strength with our consumer connection. So your question about our consumer, the fact that we gained 6% in total members, our retention is healthy, we're moving more members up into platinum and diamond and retention of those guests is very high and our brand love reached an all-time high. The connection to Ulta Beauty is strong and we're managing through this really again, unprecedented competitive environment. And all the things I talked about, our confidence in our model, our confidence in the health of this category, and our ability to adapt and adjust our strategies and initiatives, as I discussed, give us confidence both in delivering the updated guidance, but I'd say even more importantly, the future continues to be very bright for Ulta Beauty because we're well positioned with a strong share of the category, strong connection to consumers, and the ability to navigate and adjust our plans as necessary as we've been doing throughout the history of this company. Paula, do you want to talk then about merch margin?
