Cordial price changed multiple times in the last few days

[Dirich]

1-2 weeks ago I bought ~50 cordials at 200 GC seals each.
2-4 days ago I found out the price was 2000 GC seals (note that I couldn't have bought 50 at one time if the price had been 2000, so I am 100% sure it changed).
I thought this was just a price change on your side so I didn't report it.
Right now I just went to the NPC again and the price for Cordial is 500 GC seals.
I have no idea if all this variation is meant to be or not, so I'm reporting it since a double price change in few days is odd.

Are you sure you aren't remembering the price of Ventures with the 200 price? Is it possible that the 2000 was just you trying to buy 4 cordials at once?

P.S. Materiel is a term for military supplies and equipment, so it isn't a typo.
