Partly depends on what kind of case you want and probably how many you want. A cost for empty cases can be postage.
But there is probably a few people out there like me, who re-house there discs into cases that hold more discs or even just re-house to DVD wallets, and hence have spare cases.
UK 14mm 1 or 2/3 disc probably (or disc trays) you can probably find someone selling a bulk buy of them on ebay. You may not be as picky as me but there are some older generation of Amary cases that have, I'm gonna call prongs that when disc release is pushed makes an indent in the art work (wouldn't recommend them but I have a bunch of those spare and pretty much like new).
And in some case it just cheaper to buy an actual an actual film or a 3 set film box or TV series
It's a while since I've used them but for 4-6 & 7-10 way case "Dragon trading" on Amazon or ebay (price do vary between the site so worth a check on which is cheap for the one you want).
But again it can vary on how many your wanting and what kind.
Just wanted to say that I followed your advice last year and purchased some blu-ray cases from ebay.
Here's another link to consider:
