There is a real issue with impact on small scale trading. I buy most of my stuff off auction but occasionally I'll put the call out on the trade channel for residue or resources. Sometimes the quantities individuals have to sell are only a few pedTT and have low mu. If they have to pay 1 ped to get to me to trade, then the either take a loss on the sale or I pay significantly higher MU (and why would either of us do that). So sales of small stacks will take a hit. Of course there are ways around this but those ways are only really viable options for players with a bigger budget.
