Does Renderosity help merchants by identifying volume price points for product segments?  Given the amount of sales data available to them, this would be relatively easy.  Believe it or not, ultimate sales for a given product can be fairly accurately predicted given such a rich data source.  If this isn't routinely provided, then merchants are just shooting in the dark with their pricing approach.  The goal normally would be maximum return for a product.  Therefore, knowing that a texture set for a dress (knowing how many of the model sold say in the first week would probably be a strong indicator of ultimate market size) sold at what multiple or factor of the model given a certain price point would be very helpful.

1 @ $100 = $100 total sales
200 @ $2 = $200 total sales

This lays out as a curve with sales and units as the axes.  Simple stuff really, but the data aggregator has to make the information available in order for the vendors to benefit.
