Spain's Renfe discount train ticket questions

[to2leo]

Hi everybody,

Don't know if anyone can help me about last minutes discount prices for Spain's Renfe train tickets.

 

I will be going away for my annual month long trip in April.  I am wondering if anyone has any experiences in booking last minutes discount tickets from Renfe train?  How does it work?  Where can I find it?

 

Any help is appreciative but if you don't know it is okay.

 

Thanks beforehand
