Come September we're going to have 4 kids at the same independent school (we currently have 1 but have decided to send the other 3). I asked about sibling discounts and got offered 5% off DC2, 10% off DC3 and 15% off DC4. I know another family of four in the school and they're getting 100% off DC4 (the Mum told me after she'd had a few vinos). Can't decide whether to mention this to the head / attempt to negotiate. What do other schools do? Has anyone else successfully negotiated or is that just really bad form?! Thank you...
