Answer:
impulsive shopping
Step-by-step explanation:
Impulsive buying is one that you didn't specifically leave home for, but ended up doing because you considered it a good promotion, something you longed for, or simply because you felt like it. In practice, imagine that you left home to pay some slips. On the way, you passed a shoe store and saw a nice pair on sale. It was not in your plans to buy them, but you wanted to take the opportunity. This is an unplanned purchase. That's exactly what happened to Melanie. She left home exclusively to buy a gift for her brother, but returned home with the gift and a pair of glasses, which she had not planned to buy.
