It takes 6.375 days to walk from 342 Euclid Ave in Cleveland, where I ordered my shirt from, to 215 Willoughby Ave in Brooklyn, where I live. Walking for 12 hours a day, that’s still only 12.5ish days. However the USPS must have found a form of transport even slower, because it is currently day 16 and I am shirtless (I ordered it on the 6th).
