At one point the price of these was 200g and in my log it showed I bought them for 850g!
Seems that someone else had bought the cheap one and the price displayed to me never updated. In fact, I bought one for 200g and it seems like the price to buy 1 more just never refreshed on my screen.
Please address this ASAP!
PS: the auction log need to be made chronological minute to minute, mine is totally messed up ATM.
