We have a 1/4 mile long gravel driveway with a fairly steep incline the first 100 yards. For a time it was not very navigable by trucks. Fedex had no problem, but we had an agreement with UPS to pick up our stuff at their distribution center (in town). But we’ve fixed it so no problem.
And it turns out they have an agreement of some sort with the USPS. We now get deliveries at all times - even Sundays - in our mailbox. We have the large style mailbox for just this reason.
Bottom line is that it is not an issue.
Thank you. Sounds like I can continue feeding my Amazon fix.
