Where do you buy your CDs these days?

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!). 

I have a few CD's I am throwing away. I got my old CD's and SACD's out of storage and set them up on my CD rack. However, the extras that did not fit on the rack are going to be removed. I see that Goodwill may take these CD from the posts on this thread.

I have a bunch of Stereophile audiophile recordings from maybe 15 years ago. I never listened to them much but someone on Audiogon may like them. They are free to anyone who wants to pay for the shipping.

If your getting 1.99 plus shipping...your getting top dollar.You don't  even have cases .I buy ebay,but want a case .
