@bigtwin: The Amazon packing you are seeing in Canada (a thin cardboard mailing sleeve inside a 4" thick carton filled with bubble wrap) is the same I have been seeing for quite some time here in the US.
That's certainly preferable to the mailing envelope they were using a few years back, but I'm still seeing damage in another way: While the double-boxing guards against shipping damage, what I'm regularly receiving are LP covers which have been bent/creased, a result of pulling them from the storage racks in the Amazon LP warehouse by the corner of the cover, rather the center. Duh.
I return, like others, maybe about 25% of my LP's for new copies. Most of the second copies arrive undamaged, but I've had two titles where the second copy is damaged in exactly the same manner as the first. Double duh.
Analogue Productions/Acoustic Sounds, on the other hand, packs with extreme care. Elusive Disc is real good too. Almost all Discogs and ebay sellers ship LP's in those pathetic thin cardboard mailing sleeves, which do little to protect the corners of the LP covers.
