I've exchanged my Tescos vouchers and had more than I thought 
DD1 (8) would like Harry Potter Lego or Playmobil. I have enough vouchers for the big castle
but after a quick looik she likes the quidditch set and a vet playmobil set (I told her I was looking for a friend's kid). She also liked Hogwarts Express (but has never really been a vehicle person)
I think one big set would have more playability but wondered if anyone had any advice
I just want to get it ordered now (vouchers waiting and itchy fingers and all that!!)
