Using a descriptive–correlational design, the research analyzes respondents’ purchasing frequency, preferred product categories, unit sizes, average spending per purchase, and access to retail channels that enable tingi or sachet buying. Statistical tools such as the median, chi-square with Cramer’s V, and Spearman’s rank correlation were employed to determine the level of influence of demographic and socioeconomic factors on buying behavior. Findings reveal that unit-based consumption remains a practical and adaptive strategy that allows households to maintain daily needs despite financial constraints, with sari-sari stores serving as critical access points. The study highlights how affordability, shape purchasing decisions, manufacturers, and policymakers seeking to balance accessibility, economy, and sustainable packaging practices in low- to middle income communities.xx, 278 p. : ill.
