The same product that arrives at the same chain stores on the same day may be priced differently. Different locations may mean different overhead costs, such as one location having higher instances of shoplifting -- everyone who shops there bears that burden in the higher prices. The grocery store in the plaza I worked in had the highest meat prices of the chain because there was a homeless camp in the nearby woods. Too me, all they had to do was ask those men to take off their overcoats. They just are not need 99% of the time in Central Florida!
