Validation of UTAUT and UTAUT2 scales for deal sites

Deal sites, in some form, exist already for over two decades. They became well-known in the last, approximately, decade. But there is still only a limited number of papers investigating their adoption and use from a customer perspective. Most of the research published on the topic is qualitative, that is usual for an early stage of investigation of anything. The Unified Theory of Acceptance and Use of Technology explains adoption and continues usage motives. The aim of this paper is to validate scales for the first and the second version of the Unified Theory of Acceptance and Use of Technology for deal sites. This should pave a way for quantitative investigation of motives for purchasing using deal sites. With regards to the results, eight of ten validated constructs could be used as they were designed, one could be used in a shortened form with caution and one is not truly suitable in the tested form.
