Where do you buy your CDs these days?


I'm curious what online sites folks use to find CDs? I use Amazon, and especially their Marketplace sellers for used discs. But prices have become high and supply has become stagnant. I used to use several European retailers (Amazon UK and Presto) before the pandemic, but shipping is extremely slow these days and I've had more than one never show up at all and presumed lost. Surely there are other online retailers?

I try not to give money to Amazon. 

I second the recommendation for discogs, too, though the site design is not awesome.

You have already got a lot of recommendations about buying cd:s. If you want to buy downloads you can try HD Tracks.

You will still "own" the music you have bought and it should work as long as there are equipment to play it on and that will probably be longer than there are cd players. You do need a player/streamer with storage or a network attached storage (NAS) that your streamer can get the music from.

I buy all used CDs on eBay. It usually ends up being from declutter. Low prices, low or no shipping, fast delivery. I research via the DR database first to at least rule out the bad/compressed recordings. Most 'remastered' CDs are worse than the originals, sometimes waaaaaaaay worse.

I buy new CDs, usually only new artists, from Amazon. They almost universally cost too much and are almost universally DR compressed. I know this going in and a lot of what drives buying it is to support a new band. Not sure how much they get per CD. Maybe nothing.

I just got a SACD player. Not sure I'm going to go down that path unless it is something really special.
Second Amazon/eBay, but I only buy new or pristine CD's nowadays because my Cambridge Audio CXC transport hiccups at the very hint of a scratch or scuff, whereas my Oppo BDP-103 would play with nearly a complaint (AND it played SACD's, too!).
