Considering they are mostly a middle-man, that's a high compliment.

To their credit, they use a five digit part number. If someone on the
Internet were to say "their 12345 product gave a good result", if
you bought the 12345 product you would see the same. They likely source
all of a particular SKU, from a single manufacturer. So if the product
was made by Ritek, and was 12345 Verbatim, then buying that a year
later it would still be Ritek and with the same media tag.

Verbatim seems to own some physical facilities now. They may have
acquired a company that makes jewel boxes for housing discs. They may
have acquired M-Disc factory (only part of it). A few other things
would still be the arms length, buy-a-lot-from-a-factory type business.

It's unclear, why more of the foreign suppliers did not do direct marketing
of their own. Ritek could easily have purchased cake boxes and packaged up
their stuff, shutting down innumerable middle-men as a side effect. But
they didn't do that.

That's why, one year, Ritek was only available as stacks of bare
discs, *wrapped in Saran Wrap*. Surely the most stupid packaging exercise
ever practiced by my computer store. And that's because Ritek never ever
put their stuff in a cake box. When the end came, they sold raw discs,
and the store didn't have cake boxes either, so they used Saran Wrap.
Did the users buy those that way ? I don't think so. You can't hump
Saran wrapped piles of DVDs around your livingroom. They will spill
all over the floor.

At least Verbatim has cake boxes. But the media itself comes, most
of the time, from someone else. It's only at the collapse and end
of the industry, that Verbatim has acquired small factory setups of its
own. Because, no other supplier could stretch themselves to take
these factories "into the fold". One of the factories, has
competing employees working elbow to elbow, as a "joint venture",
until the market is gone at least. More cats sleeping with dogs.
Rather than throw the equipment away, the factory doubled up,
the employees went with it (because the chemistry is a trade
secret and some of them know how to make discs).
