I was e-mailed this promotional idea from the RAB daily e-letter… 

This promo, called “Cutting Your Green Fees,” runs in two phases. The first, month-long promo involved a fertilizer product who, as a sponsor, received on-air mentions as well as in-store signage. Listeners who purchased $25 worth of the products from the farm supply store, (you could use any local Lawn & Garden Store), received a free bucket of golf balls from a local driving range. A $50 purchase earned a free round of golf at a local golf course. The second month-long promo involved an in-store registration for a free lawn mower courtesy of a power equipment vendor. The twist here was that the winner of the lawn mower had his/her lawn mowed by the station’s sports director/on-air personality. The drawing was broadcast live from the participating retail
er, who enjoyed record-breaking sales during these promotions.
