Realistically, there will be some retailers that know this info well because they care - these retailers tend to do well and stay in business for a long time. Then there will be those that would like to have some of this info but either don't have the resources to attain it, or are ignorant as to how to attain it - these retailers will often take 2 steps forward and 2 back, always trying to catch up to industry leaders. Then, yes this segment exists in real life, you will have retailers who just don't care - and I suspect many of you know their ultimate fate.
