Many birds with one stone

I have been wondering for some time how I could get more customers effectively until I went to the gym at Good Life.
I really like what these guys do to get new customers; they hand out FREE one day passes that you as a member can pass on to your friends and have them go with you. This is just amazing and benefits everybody: you as a member are happy because you can bring a friend; your friend is happy because they get FREE pass and Good Life is happy because they got you to find and bring a new customer to them at what cost? only $2! where that customer could pay in membership fees over 5 years more than $3,000. THAT’S SMART!!!
