Can someone explain this concept to me or point me in the right direction? I consider myself pretty decent at playing the AH but this has never made sense to me. Is this only for mats with small amounts? I.E. You can't do it with cloth because 10 people come along and undercut you. You can't just re-list your stuff at the same price and expect it to sell. I'm under the impression that the big money guys have one set price that they always list their items for. I do it the exact opposite. I buy all the cheap stuff and list it right under the next "gap" in prices. Like if there is copper ore 75s and below per piece, and then a gap up to 1.5g per piece, I'll buy all the 75s and list it at 1.49g. (Provided there isn't a ton and I think it will all sell)
