The marketplace is soooo overrun with delears and retailers selling games, I think it should be split into different groups. Atleats new and used and perhaps split for dealers and individuals.
Or even ban any blatantly obvious traders on the site. They have their own facilities to sell games through - why swamp those of us who are trying to sell the odd game on the site now and then!
This should be a serious consideration for Aldie before the whole marketplace collapses under the sheer weight of offerings.
