While I sticky tape the envelopes these go out in, please note that Australia Post use automated mechanised facilities which occasionally cause these links to be damaged in the mail. If this occurs, please advise and I will post a fresh one.
Please note, I normally post the day after the sale. If any delays, most likely AusPost. If Australia Post charges for underpaid postage, please contact me and I will contact AusPost as I use "uncancelled" First Day covers for postage.
