Door to door shipping (USPS, etc.) is all but done for the season. I’ve found that if the temps will be below 20 degrees (and they usually are at least at night through February around here) that door to door shipping just isn’t safe. Usually things don’t warm up enough until March for me to be able to offer door to door shipping again with the possible exception of a warm enough window that normally happens in January or February.
That said, as weather allows, I can still offer air cargo shipping on Southwest airlines for much of the winter.
