Buying something from Spain but need an address there?

Hey folks, as random as it sounds, I have located a toy that I wanted to buy for my son for Christmas, it is rare (more discontinued than rare) and the only place I found it was on Amazon spain! And the seller does not ship to the UK.

I tried to call them, which ended up with the person speaking Spanish and me asking in English, which understandably did not provide any solution  

Does anyone know of any one-off services whereby you can send to a Spanish address and have it forwarded here that doesn't cost a fortune?

 

Please Help !
Thanks !

I didn't find the right solution from the internet.
