The "cost conscious" option in a city with one of the highest median incomes in the US is very different from a cost conscious shopper in a city like Daytona Beach, where practically a quarter of the population lives below the poverty line!

I will also point out that "cost conscious" is one of several shopper profiles that Safeway targets, but broadly speaking Safeway targets a more affluent shopper (although cost conscious isn't the same as non-affluent). The degree to which a particular location services these targets varies by area. But no, these stores target fundamentally different shoppers and think very differently about assortment, at least with regard to the long tail
