I have had nothing but problems with sending CD's to Australia and I just had another buyer contact me tonight asking where her CD is. They were all sent light packet from Canada.
I sent:
CD sent November 14/16 received by buyer in Australia Jan 9/17
CD sent November 21/16 received by buyer in Australia Jan 9/17
CD sent November 21/16 not yet received buyer said he is just starting to receive CD's he purchased around the same time as mine so he wants to give it a few more weeks.
CD sent Dec 5/16 not received, buyer contacted me tonight.
I asked the buyer to wait a little longer and gave her the above dates. Buy they definitely don't make ebay's estimated delivery dates.
I have since blocked Australia.
The Australian buyers have been excellent, so nice and patient. It is too bad that their mail system is such a mess.
