I have heard a few people talking about Student discount cards. I'm not sure exactly what they are or how you use them.
If anyone has more information about the student cards ie. where I can get one, find information on them, or what kind of discounts I could get with one in Spain that would be great!
There are several official and well recognized ones, and you should be able to find details just doing a google search. If it helps, i had an isic card for years which was quite helpful
It's generally potluck where accepts them and not, but many museums etc offer student discounts on production of a recognized int'l student card. Some other places as well, and they have extra benefits as well (some have a freephone answer phone, for example).
They're also great for getting discounts off organised backpacker ventures like bus tours etc. I've already saved more than what it cost me just by using it on my next trip!
