Do you have anything in extra-medium?

This is so true. I have gone shopping for shirts, for shorts/pants, and for shoes. I am shocked at how often stores allow themselves to run out of Large and Medium sizes.

I go shopping for shirts. I find a great sale on some shirts, oh boy, and look, they have S, XXL, XXXL sizes, and nothing else. For every color of that shirt, all 17 of them.

I go shopping for shoes. I talk to the salesperson and let them talk me in to a few shoes. They have none of them available in size 11.5. I have to settle on the 5th best choice, because I can't even try on the other shoes.

This happens regularly. I'm sure this is not a new occurrance. How can the stores not be prepared by now?
