I would also like to point out that, although I cannot stop anyone withdrawing from the order, it does have a knock on effect.
The Bankroller's liability has already increased due to people pulling out and if the Bankroller is not prepared to fund the extra then prices will have to increase to cover the shortfall. This means extra time and effort as I would have to collect underpayments or further people may withdraw as they don't want to pay any more. This in turn could jeopardise the whole order in which case I would have to make refunds.
I know this is closing the stable door after the horse has bolted but I think it's wise to make you aware of the impact of withdrawing from the order at this late stage and to bear this in mind when putting your name down on future orders
