Unfortunately, if you have an urgent package to mail out on Saturday, driving it to its destination may be your only option. In addition to the USPS, both UPS and FedEx will be closed on the Fourth of July. FedEx Home Delivery will be delivering packages on Friday, and UPS will be open for business as usual on the 3rd. T-minus 7 days until 4th of July. Red, White, Blue and better than you.
