I'm looking for DVD-cases that hold 6 discs but are as width as a single DVD (14 mm). The only shop I found some is HERE:

Although these do look a little fragile (and some of the discs are overlapping, which isn't the best solution) I'd be happy do get some of these. Unfortunately I'm located in Germany, and shipping alone would add up to $ 80, which is "a little" too much for my taste.
Nevertheless, there are other single-width-6-disc-cases (what a word), like with the RC2/RC4-release of "Magnum P.I. - Season 2", which uses a system similar to this:

... but at single width (and with white flaps instead of black ones). The image above shows the standard 6-disc case with a width of 24 mm - 27 mm (depending on the brand), which I'm using for my 6-disc needs (like replacing TV-show digipacks and stuff). But having those at single width would be just fantastic.
Does anybody know where to get the "Magnum"-type cases? And is anybody willing to help me defy those ridiculous shipping costs by ordering some, and forwarding them to me (which might still come out cheaper than $ 80)?
