Iddee suggestion is very practical, since you have a very charming personality.
A question to ask when inquiring about free delivery is whether they will ship to a post office box or do you need a street address? The UPS store has all the conveniences you are looking for, I think. With a box rental they offer you a street address. You can call in advance to see if your packages have arrived. The UPS store will hold them for you until you can pick up. I copied this from their web site:
Your mailing address will be the address of The UPS Store location, with either PMB (private mailbox) or the pound symbol (#) designating your individual box. Instead of “The UPS Store,” your name appears first.
Example:
Joe Smith
PMB XXX or # XXX
12345 Somewhere Street
Some City, Some State Some ZIP
According to the UPS store finder, the closest location to you is Augusta, Maine. I don't know the terms of a box rental, however. So, this is only a suggestion.
