Our USPS in the midwest is not reliable at all. Arrival dates come and go. USPS trucks go 1 1/2/ mile by my house to 140 miles north to Fargo then back to Huron, SD(90 miles SW of me) then to Watertown, where I live. Sioux Falls is 100 miles south of me, took 5 days for a small package to get here. I woouldn't use them.
