I have a question, the amount of materials in an auction matters? lets say 1 of 1000, it will sell the same as if I make 10 auctions of 100 each?
Depends on what item I put on sale.
High tier gems: I sell individually, as probably people don't need 10 radiant star.
Essences: I put on 10 or 100 together, most of the time the smaller pack goes faster.
Tomes/pages: I sell 100pcs together at least, usually goes fast.
But honestly, I'm still learning gAH, so you might find out better tactics.
I don't mind selling in small amounts, but the system for the commodities is weird and I didn't know one person have to buy for everything, I thought for a moment that if I set an auction with 1000 gems then it would sell to more than just one person...
