I think a monthly fee should be scrapped and I would encourage a parent to write to the school to petition for this to be the case, especially in this climate. Some schools offer a saving 2-5% if you pay the whole yearly fee in advance but we worked out (not that we could have afforded to anyway) but I worked out it would be better to put the money in a savings account (pre the interest rates dropping).
Why would you want a monthly fee scrapped? - I think it helps some people with budgetting and spreads the cost through the year instead. If you could have got 5% discount in recent years it would have been well worth taking - very few savings accounts gave 5% after tax.
