You're brave for going to this shop OFTEN! I'm back back next summer, but I'll go only once (and go back to this wonderful shop with the rare stuff XDDD)
I'm glad I could help and give some informations to your friend, when I went there, I just only new about the waiting are and the long time you spend, but didn't know how it worked inside, so I would have prefered knowing this earlier (even if I managed to get what I wanted anyway XD)
