Sure. As far as on the keyword pricing, et cetera, I'll answer that, and then Mike can talk about merchant. The 21% increase in sales and marketing wasn't necessarily all keyword pricing. But it does reflect an increase in aggression on our part in the CPC space and search engine marketing in general. Both and are being very aggressive than some of the new territories that we're going into, new markets in Europe, Asia-Pacific, where we go in with more aggressive efficiencies, so to speak. So that's not necessarily keyword pricing going up. That's just our getting into new markets, which tend to be less efficient from a marketing perspective than, call it, our more mature markets where we have more repeat users, et cetera. So I think while there is some keyword pricing in there, while we are, on balance, being more aggressive in certain markets and we do anticipate being more aggressive in the European, Asia-Pacific markets, it's a combination of our getting into new markets and our being more aggressive on the keyword pricing front. As far as ROI goes, as we get into these new markets, as we increase our spend, our ROI is lower than, call it, the mainline spend that we have in place now. So my expectation will be that for a couple of quarters as we spend up, our CPC ROI will go down, and then what we do is we spend time optimizing the ROI there, understanding which keywords work, understanding which keywords don't, optimizing our landing pages, the presentation to the customer, which usually gets us some efficiency back. But right now, we're in a mode of spending up. You see it in our sales and marketing numbers but also, again, it's something that we manage and you see it in our revenue numbers and gross bookings numbers, which are quite healthy.
