I was about to suggest FactoryDirect too, as they have computers that are refurbished (ie. much lower cost), and it is possible to buy insurance on them through the store, in case it breaks. Normally I wouldn't recommend tech items from a refurb store, but you might be able to find something with a CD drive.
Another nice store to check out is https://www.wintroniccomputer s.com/
JusticeBeaver's suggestion of an external drive is a smart idea, and what I would recommend. When would you actually be using the CD/DVD drive? I had one in my old Macbook Pro and thought I would use it but now, with cloud storage and android/chromecast, I've never needed to burn DVD's for storing files or movies in such a long time. Same with CD's... with Spotify, I haven't burned a CD in over 5 years.
Here's one on Amazon for fairly cheap:
