The results of this Literature Review article are that: 1) Price is related to Purchase Intention; 2) Trust is related to Buying Interest; and 3) Advertising related to Buying Interest.

RESEARCH METHODS
The method of writing scientific articles is by using qualitative methods and literature review (Library Research). Assessing theory and the relationship or influence between variables from books and journals both offline in the library and online sourced from Mendeley, Google Scholar and other online media.
In qualitative research, literature review must be used consistently with methodological assumptions. This means that it must be used inductively so that it does not direct the questions posed by the researcher. One of the main reasons for conducting qualitative research is that the research is exploratory, (Ali & Limakrisna, 2013). At the next stage, it will be discussed in depth in the section entitled "Related literature" or "library review" (Review literature), as the basis for formulating hypotheses and in the final stage these two literatures become the basis for comparison with the results and findings. -findings revealed in research (Ali, H., & Limakrisna, 2013).

DISCUSSION
Based on the theoretical study and relevant previous research tables, the following discussion is discussed:

Relationship of Price on Buying Interest
