Question

what habit should consumers avoid when using coupons?
○ buying in bulk
○ comparing prices
○ buying on impulse
○ using credit cards

Explanation:

When using coupons, buying on impulse is a bad habit to avoid. Buying in bulk can be reasonable if the product is needed and has good value. Comparing prices is a smart consumer habit. Using credit cards is a payment method and not a habit related to coupon usage that needs avoidance in the same context as impulse buying. Impulse buying with coupons can lead to purchasing items not actually needed just because there's a coupon, wasting money or resources.

Answer:

buying on impulse
