I can talk about Costco; I'm not here to talk about the others.
I will say that Costco is working very hard. On a daily basis, our team looks at what we can do to gain and maintain the trust of our members. When somebody decides, as you said, to pay to come to shop somewhere, you have to offer something. If you don't give them the pricing and the quality, why should they pay to come to shop? That's our basic philosophy and our basic concept. We're going to continue as best we can to do that on a daily basis.
I will say the “utopia" of Costco is to be able to sell merchandise at cost and to make some money with the membership and other things. That would be the best. If we can do that one day, that's the utopia, and it will be good for us. It's not easy to do, but that's what we're aiming for.
