A customer buys the same brand of toothpaste every month without comparing alternatives or actively thinking about the decision. This is best classified as:

Correct Answer: B) Habitual buying behaviour — low-involvement, routine purchasing with little conscious brand comparison — the purchase is routine, low-cost, and made without active comparison or conscious thought — exactly the pattern that defines habitual buying behaviour. Why the other options are excluded: • A (complex) applies to high-involvement, infrequent, high-value purchases with significant research — the opposite of routine toothpaste buying. • C (dissonance-reducing) applies when a buyer perceives few differences between brands but still feels some post-purchase doubt on a bigger-ticket purchase — not routine low-cost items bought without a second thought. • D (variety-seeking) involves actively switching brands for the sake of trying something different — but this customer sticks to the same brand every time. Example (Pension Sector): By contrast, choosing an NPS Pension Fund Manager is a textbook case of complex buying behaviour — subscribers typically compare fund performance and consult advisors before deciding, unlike a habitual toothpaste purchase.
