Sure. Thanks, Rodney. Thanks for the question, Rob. Yes. I would say, Rob, obviously, when we guided at the second quarter, we said that the gross margin contraction could be similar to what we were seeing in Q2. And I would say the dynamics that are in place haven't changed dramatically. Obviously, it's a dynamic environment that we're managing, and our goal, as Rodney mentioned, is to continue to find sourcing benefit and savings to offset the cost increases where we see them and to pass on pricing where it makes sense but also to keep investing in the customer. And I'd say that we -- in Q2, we were doing that. In Q3, we've continued to do that.
Supply chain would have been a similar sort of headwind in Q2 and Q3. I would say we were successful in mitigating some of the cost increases in shrink during the quarter, which helped during the quarter, although we still think shrink is a dynamic metric to manage based on some of the organized crime that we see in shrink. But overall, we were pleased with the progress in shrink during the quarter. And I think, for us, we kind of guided, while we never get into specific numbers on individual gross margin and OG&A metrics because, as Rodney mentioned there, our goal is to be dynamic in managing it, ensuring that we're delivering sustainably for our customers and growing loyalty while also being able to improve profitability over time by managing the different levers across selling growth rate, cost of goods savings, taking cost out of the business and continuing to grow alternative profit streams.
So I think it's a dynamic environment we continue to manage. I think somewhere between the Q2 and Q3 range is where we think that we're operating right now. We think Q4 would likely be similar to what we've seen in Q2 and Q3. And as I mentioned in my prepared comments, we are increasing some advertising in the fourth quarter to support the accelerated growth in some of those new initiatives.
So I think, again, I wouldn't be guiding to a specific number, but in the range that you've seen in Q2 and Q3 is where we feel comfortable in managing the business and driving the right balance of sustainable growth for shareholders while continuing to win customer loyalty over time.
