[Negotiating Offers]

I had to a sign an "Intent to Register" form.  The only thing I would lose is the deposit I put in.  I agree, I really dislike how universities strategize their offers. 

[Negotiating Offers]

I was recently accepted to two of my top choice schools and decided to choose school A over school B.  I wrote school B an email to thank them for everything and they wrote back saying that they regret my decision and are offering me a scholarship to cover more than half of tuition if I decide to go there instead.  Having that much less debt is a huge draw, but I have already accepted school A's offer and the reasons I was more drawn to school A are still there, so would it be distasteful and immoral to tell school A about school B's offer and ask school A what else they can do to help me out financially?
