Sure. So, on free cash flow, the way I would think about that, I would expect free cash flow in aggregate to generally trend with our trends in adjusted EBITDA. So I would expect that you'd like - you're likely to have similar levels of free cash flow as you have similar levels of adjusted EBITDA. With regards to working capital and Groupon Plus, as Richard highlighted in his shareholder letter, you see us over time leaning to a greater degree generally in card linking. Card linking has different constructs, not all of them are the existing free-to-claim model. And with that the working capital dynamics could be closer to our traditional voucher product. So the overall thought there is, is I would not expect a material negative headwind from the transition to card linking, and I would just say, in aggregate, I would be thinking of our free cash flow as, in general, this year, next year, over time, generally trending with our trends in adjusted EBITDA. With regard to how we think about marketing in International and how we think about marketing in North America, I would separate the two pieces, and Rich touched on this a bit earlier. In International, we are still in early innings. I mean, we still have a large untapped market of over 0.5 billion potential customers that we have the potential to acquire. And what you see in International is, we're able to acquire customers and at the same time, maintain a high quality of customer and you see that through GP per customer, where generally the trends have been GP per customer increasing while we add customers, which is not necessarily an easy thing to do, but highlights just the value of the customer on average that we're acquiring. In North America, I think there's a couple of things you have to ultimately tease apart. One is, we are very focused on making sure if we invest a dollar in marketing, we receive an adequate return on those dollars. I mean, Rich has said this before, we're not going to invest a dollar and get less than a dollar back on that. I mean, we want to make sure we get an adequate return within a reasonable time period and we see that, and we continue to get increasingly granular and refined in our customer and retention acquisition efforts. And with that, you see some declines in our customer base. Now, the other thing I would add is, obviously, our customer base is also influenced by the trends in free traffic as well and that influences it as well. But we're going to be very disciplined and appropriate with our marketing dollars, to just make sure we're getting good returns for those investments and lean in where we can get good returns.
