In my area - toss up as which is best. FedEx is always early in the day, and if it's in-house, they deliver the package, even several days sooner then scheduled. UPS is always late - as late as 8:30PM, but normally around 4-4:30. They will deliver on the SCHEDULED date only, regardless if it's in-house. USPS is usually pretty good - that is if their tracking system is working. As far as USPS schedule...... I'm waiting on parts - and via all three. Oh well, lots of other things to do instead - like rake leaves, paint window sills At least no acorns this year - squirrels aren't happy
