Help me get an Interrail ticket for a needing friend!

Interrail is one of the most amazing travelling experiences one can get. Especially if you're young and curious about the world surrounding you.
It should not be an obstacle the fact that you don't have money to pay for it, while all your friends do.

Please help my friend get an Interrail ticket. Help me raise a part of the needed money, I'll pay for the rest of the ticket myself. He does not know this is happening so it would be a huge surprise for him for this Christmas!
I'm taking every kind of donation, I would be so grateful if you could help me get some of the money to help him!!
