Ahh the question that i was thinking of asking myself just a week ago... But then i changed my mind strapped on the walking shoes and went out flyering the neighborhoods in the cold dreary weather. I was a little concerned with the cost difference between my standard flyer, and the cost of printing and mailing the postcards. I know as a consumer that i generally just glance at them, and unless it has something to do with my business, or something that i had already been thinking about doing, rarely do i glance more than once. This scares me off of this tactic. The success rate for flyers is very low, like 1% low if that, if the success rate for postcards is <1% than not worth it to me. They are semi costly to print, and even more costly to mail. Just my $.02
Although i seem negative, next year i am having (depending on cost difference) somewhere from 50,000 to 200,000 printed off. I have found that the change in cost per piece can be so significant that it is almost stupid not to have the 200,000 vs. 5,000 or 50,000
