No!...You don't get to read that bit until after the tickets are in your hand.
i.e. After you have handed over your money, you then find out that if it is cancelled you may lose it!
Caveat Emptor dear boy, Caveat Emptor.
The onus is upon you, the purchaser, to be aware of the conditions (which are on their website) before you enter into the contract.
