Flohpalast has already four shops in different cities in Germany. The store chain calls itself ‘der Flohmarkt in Laden’, which can be translated as ‘a flea market on shelves’, referring to the shelf each individual second hand retailer rents. The shop seems to be very busy and has a great variety of interesting second hand stuff and different clients. The initiative is part of a bigger development in shopping and retailing, that we could call social selling rather than social shopping. We spot a trend of retail formulas that are based on joined forces of product providers. They collectively create a sales platform, mostly at flexible spaces and stores to be adaptable to rapid change.
