Posting to PO Boxes in Australia
Dear Lulu and Community,
I would like to know if it is possible for Lulu to send printed and published books to PO boxes here in Australia. I have used Lulu's services in the past and have loved it. I believe in the past Lulu has not allowed books to be sent to PO boxes in Australia and I wanted to clarify this just to make sure this is still the case. Previously I have been receiving my books through courier.
I now have a PO Box at my workplace and it would be more convenient for me to use this rather than my home street address. It is not a huge issue if posting to a PO Box cannot be achieved; it would just be nice as I'm not always home to receive the goods.
If you could get back to me when you can, this would be great.
