Price perception has a positive and significant effect on purchase decisions with a calculated t value of 4.223 greater than the table t of 1.984 and a significance value of 0.000 smaller than 0.05. Simultaneously, product quality and price perception had a significant effect on purchase decisions with an F value of 36.883 greater than the F of the table of 2.70 and a significance value of 0.000 smaller than 0.05.
