Sorry to hear you are closing down as it is always sad when we lose another resource for our addiction / hobby. I still always prefer a physical product as opposed to a download, legal or otherwise. I have to agree that shipping has killed buying stock items from overseas as I used to order regularly from the States & Japan but it is too expensive now. The lack of sales is just a sign of the times I think.
My daughter (36) and granddaughter (14) are both into music but neither own any CD's. My daughter has a Premium Spotify subscription and streams via her phone to Alexa and via bluetooth in the car while my granddaughter buys downloads from itunes to be listened to via her iphone. I know many others who don't buy CD's and are happy with what Spotify / YouTube provides. Maybe streaming is 'killing the music industry'.
