So growing ecommerce in the marketplace is key to being able to attract more advertisers. What we can do that some other people can't do is we can connect the dot between an ad you may have paid for digitally and a subsequent purchase in a physical store so that you can see the ad actually worked. So it too is an omni business for us.

Marketing is about values. It's a complicated and noisy world, and we're not going to get a chance to get people to remember much about us. No company is. So we have to be really clear about what we want them to know about us.

The marketplace is so important because we got to be in the consideration set. When somebody takes their phone out, and it's so easy to choose where you're going to go shop, if you don't have a really broad assortment, you're not even in the consideration set, and so that's one of the reasons why I was so convicted that we needed a marketplace all along, and others were too.

It can improve the customer experience if ads are done in the right way and we also want to make sure that we don't do anything that causes our prices to go up in our retail business.

We're an 'And' company, we're people and tech, we're stores and e-commerce, we're innovation and execution.

As it relates to brick-and-mortar, we've seen it all and done it all. We operate around the world in different formats, different brands. We've got large stores, small stores, all these different formats. So we know that space pretty well, but the e-commerce business was different.
