Pennysaver, MoneyMailer etc. are good resources to utilize. Front and back cover of Pennysaver ads works well, while inside ads I think it is a kind of a crap shot and a waste of money by my experiences. It worked well for start up professional businesses by my personal experiences as we track responses. But also, it depends on your offer. You need to select their circulation routes very carefully (i.e. income, apt vs. homes, etc). If I remember correctly, the front cover is about 600 to 700 per circulation of about 20,000 to 25000 homes. Money mailer is less than half of that, but I am sure you can negotiate it down. They will want you to sign a long term contract, which I won't advise.
