Yes, I do believe there is a yearly storage charge on top of the initial charge. We don't really have any family illness but I came from a VERY small family so its hard to say for sure. I feel guilty not doing it because "what if" they child gets sick and it could have saved them and you didn't do it??? But than again, that money could be used for a lot of other things. Its a tough decision, if money is no object than I would say do it, otherwise you have to weight the cost factor.
