Real simple.
Just go to any UPS
"STORE". NOT to be confused with UPS.
They have a store in just about every town use the store locator.
They will give you a 'REAL address' to use. Been using it for years. And they have a full service as far as forwarding etc. No membership fees. Just a monthly fee.
