Interesting thought. I am interested to see how their business model plays out for the next few years.
The breakdown of the Innova/Discmania arrangement seems to have been catalyzed by Discmania starting to work with other disc manufactures. But Infinite has ALWAYS sold lots of manufacturer's discs... that's their core business.
Infinite has been "acting like" a manufacturer more and more: the pro team, their own molds, involvement in sponsoring tournaments. Even if the manufacturing stays out-of-house, Infinite is still more than just a retailer.
i suppose technically dd did the same
they used to sell everyones discs but then quit (at least online im not sure in person)
