The results showed that Price (X1) and Promotion (X2) had a significant effect on Purchasing Decisions by obtaining the regression equation Y = 5.788 + 0.381X1 + 0.460X2, The value of the correlation coefficient or the level of influence between the independent variable and the dependent variable is obtained at 0.758, meaning that it has a strong relationship.
