A friend of mine and I have bought two 4-day-camping tickets for Benicassim FIB 2008 through their website...Well, now, that we know that Interpol and Kings of Leon are coming to Summercase 2008 we would like to sell these tickets, as we absolutely love those two bands!(see, we are from Serbia and although we would be glad to keep tickets for both festivals we simply cannot afford it

)
The thing is, our tickets came via e-mail ( .pdf format) and they have this protection device-our names and surnames written as a watermark all over the ticket...
Is there any way to sell these? I guess not

, as we'll probably have to be there , show our printed out tickets to acquire wristbands...
Any help(suggestions what to do with these tickets, useful links etc. ) would be greatly appreciated
