The thought process that went into that guideline is that we don't want to turn APC into an auction site. We do try to keep on top of all the sales and request that people put in a firm price when we notice a best offer post. We thought it best that seller is upfront with pricing and shipping costs so there is nothing hidden. We thought of what we wanted to see as best practices when offering items for sale, hence we also thought a picture should accompany the post as well. We've had very few complaints about sellers since these guidelines and the iTrader were put in place. In fact one of the shadiest sellers, the person with far and away the most complaints we had, disappeared the day iTrader was introduced. I'm also proud to say there has no been abuse of the iTrader system.
