Showrooming describes the behaviour of potential consumers to practically test favoured goods in bricks-and-mortar stores in order to subsequently purchase them via mail order.[1][2] As a result of this targeted consumer behaviour, both advisory services are used free of charge to prepare for a purchase and local retail spaces are used as mere showrooms for online retailing.[3] According to a representative online survey in November/December 2014[4], three quarters of all Germans have already received advice in a shop in order to subsequently purchase the goods online. According to a study from May 2013, electronics suppliers[5] and retailers with a range that can be purchased in many places suffer particularly from this. Retailers who mainly sell their own brands are significantly less affected.
