Which is more effective in advetising: "Call for a free bid" or "2 dollars per pane"?

What are people more receptive to? Calling to get a free bid, or having a set price laid out for them? I want to hand out flyers and advertise, but I’m not sure what people would be more responsive to. What do you think?

It works KILLER!!

Agreed, People want to see right away what they going to pay. Makes it easier to make a decision.

i tell em’ how much i charge per pane… also let them know ladder hazard fees or how ever you want to put how dangerous it is even on a 5’ step ladder.
