This is what I got back--nothing special there! I'm sure that no one will even pay attention that our card has been sent from somewhere other than where we actually live. So that makes for a waste of $7 additional postage and handling. I'm bugged!!
I e-mailed the webmaster of that website to inform them of what happened so that they could change the designation on their list. I'll keep you posted if I hear anything back from them.
So I guess my caution would be to hope for the best and expect that it may not be exactly what you'd like as you are choosing cities with holiday postmarks.
