I've been looking all over the place for these darn things, and I'm about ready to pull my hair out! I finally found 5-disc clear DVD cases, placed my order, then receive a phone call 2 days later telling me they don't know why they are still on their website, because they don't sell them anymore! Do these cases even exist, or am I completely looking in the wrong places?

Try this site. They seem to have a large variety of DVD case products. I've ordered from them before and have been very pleased with their product and service. United States Plastic Corp. Can't post the url for them or the page that shows the cases you need. Hope this helps. Good luck.

I've been looking at my usual sources, and none seem to have the 5, 6, 7 cases in clear.

It's a no brainer, like I said, check out the website for United States Plastic Corp. You can just Google it.
