Crystals A grade

can you tell me where ppl get so cheap a grade crystals?
i've checked all a grade items from luxury shop but the best price is 12407 for a single a grade crystal.

i've seen ppl selling them for 8900 - 10000 adena each (yes, i've checked. it wasn't soul ore).

is there any other way to get this crystals cheaper than from luxury?

thank you in advance for your help.

 

drops mate, drops!

 

is that the only option?
but why they are selling crystals cheaper than luxury ones? i can't get it

 

if nobody needs them i will take them for free ;p in that way you will have an extra free space in your inventory
