From Paizo Customer Service earlier today:
Arthur,
I can confirm that we sent you issue 111 on schedule. We generally allow 5-12 business days for domestic subscribers to receive their issues, so you should get it by Friday at the latest. If it does not show up by then, let me know and I will mail you a replacement. By the way, its newsstand release date is not until 5/11/04, so it should not be out in stores for another week or so.
Let me know if you have any other questions.
