Oh, I should have mentioned, the subject line was:
Invalid Address for ePrize Shipment - Wendy's Win a Wii
And part of the e-mail says:
Hello,
We are in the process of prize fulfillment, however cannot successfully deliver your prize due to the address you provided on the registration page. Please visit the web site below and respond within 10 days with an updated physical address.
It goes on to say they will not ship to PO boxes, etc. My address is not a PO box, and I clicked on the link and gave my same addy I did when I signed up. Then it gave a thank you message and said the prize will ship within 5 days. Not sure what the mix up could have been with my address though. But at least it's all set and on the way now.
