The SV Team Challenge allows customers with and without flight itineraries to use an "SV Code" to purchase both duty-free and non-duty-free merchandise through the website www.kingpower.com and the King Power application. The code can be used as a discount for other King Power dining services at King Power Mahanakhon, Pullman Bangkok King Power and Thai Taste Hub -- King Power's Thai street food court.
