Try some of your local drug stores. Or even some of the chain
stores, though they may charge something. My ex used to deliver
magazines to drugstores and often came home with an old display case
for watches, and such. Most were able to be modified to suit and
usually he got them for free.
I often took them apart and remade them to suit the current use. The
covers with the doors were usually left intact but I often revamped
the lazy susan to my current needs.
