For now there are still quite a few choices for new CDs: I have bought from presto, jpc, importcds, grooves.land, and alibris (usually from seller Classical Music Superstore aka Naxos USA). (And from Berkshire, though that’s a somewhat different market.) I rarely buy new CDs from amazon, unless I have a credit, because their prices tend to be high.
The used market is a different matter. I sometimes use ebay, or find things at local stores, but amazon marketplace dominates.
It never occurs to me to look at eBay or jpc, but my purchases come from.
Amazon (big boxes are often cheapest on amazon proper, and I have Prime for free shipping)
Classical Music Superstore (amazon marketplace, Naxos USA)
importcds (amazon marketplace)
decluttr (amazon marketplace)
Zoverstocks (amazon marketplace, nominally UK based but shipment seem to come from all over)
OxfordshireEngland (amazon marketplace)
importcds.com (sometimes their own web site is a better deal than amazon marketplace version)
Presto Classical (mostly downloads)
and the random amazon seller that has good ratings.
I used to order from Berkshire Record Outlet, but not for years.
I once ordered from a store in a place I had never heard of. Then I moved and found the store was within walking distance of my new home.
