Mitsukoshi Basement

Window shopping in a Japanese Department store is as much fun as window shopping gets. What happens in the basement before closing is that all the perishable goods go on sale. The closer to closing time, the bigger the discount. Frugal shoppers can get the best deals 5 minutes before 7pm, when the store closes.
