It costs about 51.28936 Lithuanian Litas.
You could collect soda cans and scrap metal for recycling, or mow lawns or something. You could borrow money from friends.
Then your best bet would to be to find someone with a paypal account, ask them to buy it for you, and then pay them back.
If you can't do this for some reason, you should be able to just buy an envelope and a few postage stamps. Also, don't mail him the money, mail a money order if you can. This will keep your money from being lost or stolen. I have no experience with the Lithuanian postal service though, so I don't know if the offer mail orders.
It would probably be better if you first went to the bank and converted the money into either USD or Euros.
