This seems the most suited forum for this, but happy for mods to move to elsewhere if necessary.
Since starting, Amazon Australia has shown scant regard for ensuring vinyl is sent packed protected sufficiently to not get damaged during transit.
If 1 record is being sent, Amazon AU will use a vinyl mailer. For the most part, no problems.
HOWEVER if 1 record & other media is being sent together, or more than 1 record is being sent, Amazon AU will put the vinyl records in a larger box AS IS. No vinyl mailer. No protection. If you're lucky, very lucky, it'll arrive undamaged.
This differs from other Amazon countries which, when they could ship to Australia, ensured vinyl mailers on every record, even if put in a box.
Amazon Australia have done this since they've started 2 years ago, and continue doing it as recently as last week (as I found out the hard way).
