I say at our management conferences that the amount Wal-Mart grows in just one year is the equivalent of Costco's size.

You take an educated gamble. If you don't occasionally make a mistake, you're not doing your job.

It's like heroin: You do a little and you want a little bit more. Raising prices is the easy way.

If you're going to say to all the people that you're working with, 'We want you to treat the customers honestly; don't lie and don't cheat,' it is somewhat hypocritical if you're not following the same rules.

We've always been in favor of improved wages for workers. When you have a strong middle class, they want to buy more stuff at Costco.

When employees are happy, they are your very best ambassadors.

When you hire good people, and you provide good jobs and good wages and a career, good things are going to happen.
