Yes. Rick, this is Raul. So we don't disclose the breakdown between fixed and variable, but your intuition is correct. If we were to look on Page 7 of the earnings deck that we provided and you were to look at, say, the increase for March, which was a CAC of $215 million, to April being at $574 million, that did reflect some investments, say, direct mail that were implied. Or you pick the list weeks in advance, you commit to that list, you pay for that list, and then you have to send mail to them. So even though the pandemic was already starting to take shape here, there was nothing we could do in terms of that particular list. You then start to see it come down to $461 million in May and $298 million in June because that was really when we had an opportunity in direct mail, and that was part of the optimization that I referred to, to make the adjustments even with the long lead times that exist in direct mail. So that is absolutely one of the adjustments that we've made to the variable elements. It's just ratcheting that down based on the response rates that we're seeing in the pandemic. To your point, there are other elements, say, the retail rent and the labor that we have there that also are relatively fixed elements, but what we've really tried to do is to figure out what are all the variable pieces that we can pull down, how can we shift to marketing vehicles that have shorter lead times, so digital, in particular, and then try to look at every other part of the organization to figure out how to reduce operating expenses. And I know you were focused on marketing, so I won't list those, but that has been a big effort that Jonathan has led as well, is looking at how do we reduce, not just the marketing expenses, but other parts of the business as well.
