My P.O. is pretty good about helping me find lost packages and they do care when the packages I send get lost or damaged. Unfortunately, they are not in much of a position to change things. Once right after our local P.O. cut back on hours and the delivery routes were transferred to the neighboring town where I have my packages held, the first time I got a "Hold for Pick-up" box they decided to "help" by delivering it to my house instead - along all the bumpy, dirt back roads before they got here. About the cooler/incubator - did you have to put any holes in it for ventilation?
