Why would there be any incentive to buy here? When scanning the GA/SA/Bronze area I often see prices here as over-GPA on raw books.
Sellers can certainly ask what they want, but the books I look for are cheaper on eBay. After a while it seems like my time would be better spent on other venues.
Certainly see it as a great place to sell. More profit to be sure. But if I can buy on eBay at 10% off and eBay bucks plus with the ability to return things without any problems, then there is no incentive to buy here.
I am just one buyer, but when things close here and open on eBay at lower prices, it seems like a waste of time to me.
