The GVH suspects that the aggressive sales technique applied by the local subsidiary of Czech company Alza violates consumer protection regulations.

The company has since September 3, 2015 been displaying on its website the number of people also interested in the offered product and the number of customers who have recently purchased the product.

The GVH argues that this may place psychological pressure on the viewer, so limiting his or her free choice, adding that this practice might induce sales that otherwise the consumer would not have committed to.

The GVH fined hotel bookings site Booking.com Ft 2.5 billion last month for similar practices.

The three-month investigation period can be extended by two months and then by a further two months.
