maybe i can shed some light
basiclly it's a con, it cost between 1000 and 1200 pestas, not sure about euro cost.
you can get them in san anto around surprise suprise the westend.
their ment to be a discount cards, but they can only be used in the bars in the westend ( gets you 1 free drink or a discount ), some of the san clubs on none club nights.
and if their is a discount on a club night say cream, it can't be used in conjunction with flyers, so your better of with out it and using the free flyers or getting a pr guy or girl to take you in a bar in the west end and get your free drink that way. note: all bars in the west will do free drinks
with every drink you buy opon entrance to a bar with a pr card in your hand.
this also applys to the sunset strip get a pr's card and get a free shot.
