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?
