Unfortunately, in my case, they've switched from being mostly UPS to mostly a combination of USPS and, increasingly, their own trucks. USPS is fine for smaller envelopes and packages and I even bought an extra-large mailbox to accommodate somewhat larger boxes. But USPS hates to come down my driveway (long and rough) so bigger packages often get hung off my mailbox, the mailbox door is left open, or sometimes just sent back to the post office for pickup.
