This happened several times with tanning packages. A local tanning salon would often donate coupons for free one-month trials. The station didn't have a set ratio for coupon dollar amount per minute of advertising, so the promotions department would negotiate individually with each customer. It was also impossible for the individual companies to keep track of the on-air advertising time, so they never knew if their negotiated airtime was actually in effect. These negotiations resulted in a completely arbitrary system that always erred on the side of the station. Instead of giving all the tanning packages away on the air, the disc jockeys would often keep a few for personal use, or distribute them to other station employees.
