I used UPS Store on Pineville-Matthews RD for years before giving up on the drive after I moved. Should be close enough for you. The UPS Store - CHARLOTTE, NC - Home
- pretty easy to get in and out of.
Forget about neutral for shipping though. They will RECEIVE FedEx and everyone else, but won't SEND FedEx if they are a UPS Store and won't send UPS if they are a FedEx Office store.
Don't know about PostNet. they appear to be neutral for sending. The UPS Store goes till 7pm for picking up (5 on Saturday). They have a feature that will e-mail you when a package arrives at least the one I use on the other side of town. The PostNet listed above is open till 6 during the week, 2 on Saturday.
My guess is unless you need to pickup a lot, you're not going to like the prices of I'm guessing at least $15 per month.
