Best way to go about getting a Eurorail pass?

I'm going to Spain this summer for 6 weeks and then will be traveling to France, Italy, and back to Spain in the span of 10 days. I was just wondering the best way to go about getting a pass would be? Do I order it before I leave or get it while I'm there?Best way to go about getting a Eurorail pass?
It's usual, and cheaper, to buy a Eurail pass in your home country. This is what the Eurail website says about it:



"not all Eurail Passes are for sale in Europe. Only main train stations throughout Europe sell Eurail Passes and for a price more than 20% higher than outside of Europe. We therefore strongly recommend that you buy your Pass before your trip. If you are already in Europe, we can ship the Pass to you on any European address"



Check the Eurail website before ordering as passes generally only last for 2 months dating from the first day of use.



Depending on your itinerary, you might find point-to-point fares are cheaper than a pass.

Buy it here. You would be lucky to find any place in Europe selling the Eurail passes for as cheap as they are here.Best way to go about getting a Eurorail pass?
