The cost really is $4/oz for banked donor milk, but that only covers the costs of processing and tracking for non-profit banks. I know it's a lot, but for preemies who can't handle the normal stuff that a term infant would be able to tolerate (something like CMV, for example, is no big deal to a term baby, but can kill a preemie) it is essential that human milk not further compromise their health.
And even at $4/oz, a little goes a long way for the really tiny babies. Plenty of them just get donor milk for oral care while they're still on IV nutrition. And many more babies get donor milk as a supplement because their mothers are still working on building their supply.
I donated milk to the Fort Worth milk bank ( a HMBANA bank) and I'm confident that they are a well run, efficient organization that does an excellent job of minimizing costs while they minimize risks for very tiny and very sick babies.
