Kube, you could be on to something.
Most generics distributors have hundreds of drugs they sell. I sort of doubt that there is any type of collusion going on among them, but they could absolutely be undercutting to gain market share. But this doesn't necessarily rise to the level predatory pricing (which is VERY tough to prove, especially when there are 8 different generics in the market, plus the brand).
What may be more likely is that they sell to wholesalers (PBM's) at cost (more or less), to try to gain some market share. But they more than make up for it with other products in their portfolio.
It's no different than when you see something on a display shelf at WalMart selling for a massive discount. Or you see TV's advertised on Black Friday for 100 bucks. It's a loss leader, gets people into the store, etc.
