The problem is that the price may go up or down, Do you have any kids? Or trusted family members, Or even Trusted friends?
The most ironic thing I've had to do is ask them to stop sending us money because it caused us to exceed the allowed income limit. As for holding money for us, that becomes it's own issue. Everybody is supposed to report income, savings, gifts, etc. I'd rather take the risks myself.
This could actually meet the needs of quite a few people we know in the Early Onset and Care Giver communities. If we can get past the moral irony of the whole situation.
