A customer is making a purchase decision between several prepackaged meals by looking at the nutrition information labeling to determine which has the least amount of sodium per serving.

Limited decision-making occurs when a consumer makes a quick choice with minimal information search, often used for low-cost or low-involvement purchases. In this scenario, the customer would not be thoroughly evaluating the sodium content, as they would likely rely on heuristics or brand familiarity rather than in-depth analysis.

Impulse buying refers to spontaneous decisions made without prior planning or consideration, usually triggered by emotions or immediate desires. In the context of prepackaged meals, an impulse purchase would bypass the evaluation of sodium content altogether, focusing instead on attractive packaging or promotions rather than nutritional value.

Routine decision-making involves habitual purchases where the consumer relies on prior experiences and brand loyalty, leading to little to no active evaluation of new options. In this case, the customer may purchase the same meal without considering sodium levels, as they are following a familiar pattern rather than investigating nutritional information.
