Do NOT buy interrail promo pass --- unless you are very sure that you are going to use it

Do NOT buy a promo pass, Interrail is not honest about the refund policies.

I bought an interrail pass in the promo period in September, and it was only in the payment confirmation (e.g. after purchase) that it said that no refund was possible for this particular promo period. In the general refund policy it says that promo passes can generally be refunded.
