Národná diaľničná spoločnosť, a.s. (the National Motorway Company, hereafter referred to as „NDS“) regularly warns drivers about various resellers offering motorway vignettes for a significantly higher price, charging various handling fees. Although such reselling is legal and common across Europe, drivers pay a higher price without receiving any additional service. Moreover, they hand over personal data to an anonymous operator, and the complaints process may become more complicated, too.
