P2P (pay-to-play) sites have been a PITA in the VO business since the early 2000s, trying to turn it into strictly a commodity business. It’s not. In real commodities markets, things run smoothly. By participating, buyers are obligated to get the most volume they can at the lowest possible price. Sellers are obliged to get the highest price they can, but in any case they must move inventory to make room for the next yield; the next crop. Both sides of the transaction are able to meet in the middle because while the product being traded in may be available at different qualities, at the end of the day both parties see it as categorically generic.
