There's no shortage of plausible explanations but I would like to know what's really happening. I wonder if some of the vendors have confidential internal reports that explain what's going on. Perhaps a significant proportion of women don't even look at the price, thereby encouraging shops to concentrate on exploiting those people rather than providing good-value products for the rest of the population. If that's the case, why does that group exist and why is it female? Is it because they are innumerate? Or because they're spending someone else's money? It's all just speculation until someone provides some evidence.
