If you think you’re going to undercut everyone by putting a buy order at a loss of -0.5%…while because of your excellent standings and lvl V skills you might make 1% off it or something, I’m just going to keep 1 unit buy orders right in front of you.
Well, one of the things I sometimes used to do was to intentionally drive down the prices of something, in order to force competitors to either make stupid mistakes or to get out. I’ve even had guys get so frustrated with me, that they ended up listing their items below my production costs. So, I’d buy up the stack, and then relist back at my normal price. Other times, they might not go low enough for me to want to buy up all of their stuff, so I’d park an order .01 cent above theirs (forcing them to sell their stuff for cheap), and then as soon as their order runs out, I’d adjust my prices back up to a normal price. Typically, this would make them think that selling that item isn’t worth it, so they’d move on.
