Retail is detail, and that plays out throughout the international business as well. Today's portfolio has got omnichannel businesses in Mexico, Central America, Canada, China, but we also have an e-commerce marketplace in India with Flipkart and our financial services business in India, PhonePe - those are a bit different, but the other markets have a lot of commonality strategically.

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.

I think that people that shop Walmart frequently and love the brand the most find it very natural to come to us first for e-commerce. But for others that may shop around or not have chosen to shop at Walmart in the past, you get what you earn, and our opportunity to earn their business starts with winning their grocery and consumables basket.

We grew this business with the store operators and the merchants making all the decisions, I got to be one of the merchants and it was a lot of fun. But to put the customer in charge, you have to start with design.

It was always the plan to bring things together, but just like the structure, it needed to be separate for a while for good reasons. We couldn't pick at store level the full Supercenter for a while. It's a lot harder to receive an e-commerce order and pick a toy at Christmas on time than it is to pick the strawberries every day, because you know where they are.

When everyone is looking for gold, it's a good time to be in the pick and shovel business.
