you got the movie included in the box set ? so am sorry to tell you that there is NO 30 € voucher in that case (anyway it's not a 30 € voucher but a 24.99 € = the card I mean)
the 24.99 € "carte cadeau" voucher is only for prereservation sets ...
and yeah was included in the box set but if so : NO movie release into it ...
the 30 € you might speak about is ONLY for FNAC members ...
