The web store offered a customer Early AM delivery but it doesn't seem to be available to the address the customer gave. It was also offered the choice to me for fulfillment but I got a generic error message: "This shipping service isn't available because of a technical error. Select a different service to complete your purchase." <- copy and paste of the actual error message
I decided to go through UPS's web site directly and it turned out early AM wasn't available to that address. I went back to the web store fulfillment page and chose regular UPS Next Day and it went through just fine.
