I was always very casual and loose about the state of items. I was and is fine with people sending just the CD and inserts in a padded envelope, via regular air mail. I had plenty of spare jewel cases (still have a couple of dozen). And as for items getting lost, sure, there’s a risk. But well worth taking, IMO. In the 20 years between 1995-2015, when I did most of my international online transactions, maybe 5 were lost out of several hundreds. Not bad.
But yes, I know I’m living in the past. It’s where I find comfort when things are as they are. I doubt we’ll get a vendor like “OnecentCDs” again, or any other similar vendor.
