OP has stated on several other threads that money is not an issue. e.g.:
So it seems like it is an issue of the family does not want to pay full sticker price, not that they can’t.
If financial circumstances have changed, then OP’s parents need to have a conversation with the FA office. And if that’s the case, they needed to have had that conversation 10 weeks ago, which is when OP was accepted ED. And really, if finances were going to be an ussue, she should not have applied ED, since they NPC would have shown cost of attendance.
