Note that massdrop ships via UPS Ground only. So no delivery to USPS PO boxes, and packages are just left on doorstep/stairs/bushes, with no signature required. Oh, and if there is a shipping error, they won't allow packages to be rerouted or returned to sender. So if you package gets misdirected, they blame you, the buyer, for their/UPS' ****up and you get nothing. Good lu k with Massdrop...
