I've decided that Costco panders to an "average" person that is fatter and taller than I am. For men's clothing, they do not stock small. They stock mediums to XXXL. And the mediums are usually all gone. Similarly, for pants, waist size only goes down to 32W, and length to 32L and up. It's slightly aggravating, especially when they have such cheap awesome shit.

I should move to an asian country. I would totally be L there.
