Interesting business here. Anyone know if there are companies who provide this service (price-scanning, recommendation, and adjustment according to a set of business rules) to non-huge retailers? Amazon, Walmart and Target have the resources to develop this internally, but I wonder if smaller guys might be willing to buy in to a system that lets them compete on a similar playing field...
