Cost effective phone cards in Spain

I’m still looking for the best phone card to use for local calls in Spain.  I’ve run into a wall searching for these cards online.  Most of them, as stated on comfi dot com include an outrageous 99cent surcharge for calls made from a payphone. 

Of course, I ONLY use payphones with my phone card and only this way, in addition to skype can I totaly replace my cell phone in expensive roaming zones (like spain).  What I do is go to a payphone, and make calls using a toll free 1-800, or local equivalent.  Thay way I can make the call for next to nothing (or free), and talk at low rates, 2 or 3 cents/minute.  Last time I did this, I managed to squeeze a 10 dollar card for near to 3 months.  I’d like to redo this in Spain, and elsewhere in Europe thereafter.

WHAT CARD AM I LOOKING FOR?
