Think of other products, services or people that you could tie in with.
Tie-ins not only save on costs, but they also give all the brands involved more eyeballs than they would get on their own.
The trick to a successful tie-in is to find things that go together like peanut butter and jelly.
A coffee brand could tie-in with a music store or a bookstore.
A computer hardware brand could tie-in with a software brand.
A luxury car brand could tie in with a brand that sells premium luggage or golf clubs.
A real-estate company could tie-in with a storage company.
Both brands need to have the same goals, the same audience and preferably the same method of distribution, so everybody has a sweet time and gets to the podium.
