Dds school only sell Radnor Splash still flavoured water or just plain bottled water. It's £1.05 a bottle, however I could bulk buy her favourite flavour for 40p a bottle. Saving about £125 a year.
Thinking on it though- they don't take bags into the canteen, so she'd be carrying a home bought bottle through the food purchasing section. So they aren't going to know it's her own from home are they?
Even if she puts it in her blazer pocket?
Am I just overthinking?
