Aye that’s what happened with my ST in Govan rear that was a long 10 years ago. My dad got the good deal then at 18 and working price up and I pay for my own@Ayrforce1
Yes happen to me many years turned 16 during the season so some were child price the rest were full price
Unless your ST is the Sandy Jardine Rear where is it 18 before full price kicks in
