I don't put prices on either. Another thing I've found is, when I knock doors after leafleting, I rarely get "how much" as an answer. Personally, I'd always ask how much as my first question if I was door knocked, but I either get a "yes please" or "No thanks" as answers.
Putting prices on leaflets or web sites can lose a customer before you've had a chance to see the job. Just my experience, others may find different.
