Thanks for the input guys. I guess everyone is thinking more or less the same thing, what really gets me is that I feel like a sucker knowing that these banks are playing on that what if scenario.
But at the end of the day it's much better to whine about a bad investment than the alternative so I'll probably do it too.
What's not really clear to me is that can the cord blood be used for the person that it has been collected from? From what I've read it seems like it is not because it's probably going to be susceptible to the same faults that created the sickness in the first place but it's really good to have for a sibling that's having problems but I haven't been able to find anything conclusive.
