There is not magic formula for marketing.If your happy putting prices on your leaflet go ahead and do it. It is your business . After all we do have different goals and businesses.For me price on a leaflet is a no no.
I don't put a price on every card I drop
I put a price which is fair and current and doesn't undercut or is cheap
I believe that there are many potential customers that will always ask "how much do you charge?" As soon as you knock, or as soon as they see you
I'm convinced that some folk will pick a card/leaflet up, see a price and decide wether they can afford it, without the awkward/potentially embarrassing conversation of having to ask how much it will be
Can't hurt to cover a few bases surely?
Like you say tho, everyone is different
