My sister sent me something that was shipped from Canton, MI to where I live in Lake Orion, MI, which is quite literally only 40 miles away. It took USPS 13 days to deliver it.

Bought something the other day and it arrived today on a Sunday by USPS. They are massively inconsistent.

It used to be here in Lake Orion, our local post office would never deliver your packages on time (you'd get "receptacle blocked" despite living on a street where basically no one parks on the street and I live on a corner anyway, and then have to pick your item up at the post office) because they just wanted to go home. But that stopped about 2 years ago thankfully.

Have always been happy with UPS. FedEx is usually OK for me also.
