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?

Usually eBay for CD's, if you know a prime member Amazon can be okay. Lp's from eBay, Pop Market and Discogs I've had a few problems with lp condition lately but usually everything is fine.Pop Market has some interesting finds in the closeout section if your willing to look and now free postage. Pre pandemic I enjoyed going to new and used stores to rummage the bins.
You can't beat Half Priced Books and occasionally Goodwill but since I've added Pandora and Spotify, I rarely buy CD's anymore and have tons I don't even listen to.
