I am going to take OP's question a bit further. I understand that Escapees offers much more, but Mail Service is a separate issue. I am hesitant to use any of these common ones as I plan to keep my residence in my current state. (not going into that here, but I have researched and it makes sense for me).
Please share experience on the mail services... Do their costs come up to about what they say to expect on their web sites? Are they really good about getting mail to right place in a timely manner from request? Do you have problems with special requests? Is it easy to see what mail you have? Determine what to have forwarded or shredded?
