ups will not deliver to a p.o. Box.
Usps will deliver to whatever address is given. Your package was sent to your street address on "clubhouse" as "ship to", that is the address you gave at the time of purchase and printed on the invoice I received for advice.
Your copy of the invoice will show "ups" in the ship via box, that is the default in our system and in this case means nothing.
All dropships from my end go out by usps flat rate except transmissions which go by ups ground.
If you need another copy of the invoice with the shipping info shown, I can email a copy to you now that I have your email addy.
