Dance flyers..refferals?

I made flyers for my dance studio. and the more people i refer...the more discount i get on my classes.

So i carry the flyers with me and hand them out to little girls...but usually i tell them "when you call, tell them that [my name] reffered you"

but i want to include that on the papers too. how do i word it though? should i just put "tell them [my name] reffered you so i can get a discount!!!" well not in those words obviously.

should i put "mention [my name] as a reference when signing up..."

what other ways can i put it??
