I posted a picture to a friend recently and took it to the post shop as I didn’t know how many stamps were needed for the size envelope I had.  I had put a piece of stiff cardboard in so it didn’t bend and the staff member told me you couldn’t post envelopes with stiff cardboard as the envelopes needed to bend in the machines? 

Hi does t recognize the P.O. Box number in that post code or town but the buyer says correct.  I’ll just send it via the shop. 

Apparently P.O. Box number is correct so who knows. Thanks for your help anyway Gary. Much appreciated.  Will take it to the post office to post I guess. 

Yes. Oddly enough if i leave out the actual po box number it goes to the next page ? Im double checking they have put the correct po box number

Also tried leaving out the suburb but it still doesnt

Hi Gary yes I have tried that but it still says  No quotes are available for these addresses. Please make sure both the pick-up and delivery addresses are correct and try again.
