Discogs takes a few weeks to update the prices but I proposed the seller to cancel the sale so he could save in fees and I could have a reduction. I don't know if that will affect to the price database in discogs. I guess we will see in a few weeks.
This is what I paid for the interview cds:
A girl like me, 35-40€
Reason, gift from a friend that came from the Spanish fan club, so free
Northern, about 20€
SpiceWorld, 15-18€ (I had it double until last month and I sold one for 23€, the UK edition)
Forever cdr, I really don't remember well because I bought it from a fan but it was about 15€, this guy sold me reaaaaaly rare things at bargain prices.
Forever Media Markt cd, about 15€
Spice, I don't have it
