When you allow a customer to describe what they are looking for and listen to the details, you can usually upsell them. Say they were looking for a throw blanket for their couch, and you suggest a matching pillow that would go great with it. Another example is someone who is looking for a mug set, and you recommend the same themed coasters to go along with it. Or maybe they have asked for a kitchen towel, and you offer matching oven mitts.
