Mail Boxes Etc offers three plans ranging from $60BZ to $200BZ a month, depending on how much mail (per weight) you are expecting to receive.
For this you receive a PO box and a street address in Miami and a mailbox here at MBE in San Pedro. Rob Henke, who runs the franchise, is great to work with.
The Miami address is good for forwarded US mail and for online purchases, which sometimes will not deliver to a PO box.
It does take about four weeks for mail to land here in San Pedro, my experience after a bit over two months. Electronic billing and payments and online banking become most convenient!
