Speaking as a non-commissioned specialist, when my shopper wants to validate our price (aka haggle), it would be nice to have our market pricing lab right off the sales floor, to show the shopper our prices are updated hourly by a scientific process and are fair.
I was part of a small project where we tried to do this.
An accurate and realtime dashboard of evaluations and inventory pricing showing how we compared to the market. We built it for sales managers, but they tried to use it for price validation with customers as well.
Ultimately, they decided that updating their prices more often didn't yield an increase in sales so they stopped doing that part, but for a while they were updating their prices 3 or 4 times a day based on market. vAuto was the primary tool used for valuations and market data.
