My wife publishes books and we ship them out media rate all the time. Our average delivery time is 8 working days (Monday through Saturday). We ship from Oregon to places all over the US. A few weeks ago I sent 7 large and heavy boxes to an address in New Mexico. It took them 13 days to get there. By the same token, I have sent smaller shipments to the east coast and it takes 5-6 days. It seems to be dependant on the size/weight of the box. Media is terribly slow but due to new postal regulations is the only affordable way to ship things like books.
