A pair of door magnets costs $80-$200 and lasts 2-4 years, while a full commercial wrap runs $3,000-$5,000 and lasts 5-7. At 15,000 miles a year the wrap earns roughly 45 million impressions over 5 years versus about 25 million for magnets — magnets win on flexibility, wraps win on presence and permanence.
