Ever seen the digital price tags at Kohl's? I can imagine a scenario where you walk in and the prices change!
More likely, though, it would be pricing things differently at stores based on demographics. Regional grocery store chains do this - We have Stop & Shop here in New England, and if I go to a store closer to an urban area, the prices are lower on some items and higher on other items.
I am in Wales, we don't have such things here. I think I'd be reluctant to shop anywhere that did this. What would be the point of working hard to earn more money if all the prices went up around you so you were no better off than before?
