I often receive a local newsletter which is nothing more than a four page print out full of about 30 ads from local companies and services. There is no text or substance of any kind. Just ads.
I can only assume that one person is going around charging these companies several hundred dollars to be included in one publication. They then distribute say 2000 of the newsletters to homes within a particular area. So they are charging quite a bit and it takes almost nothing to print these things and have them delivered.
I have often wondered how easily you could undercut those advertising fees by simply switching to a web based format. So, instead of delivering a newsletter simply post the ads on the website.
Seems like it would be an easy way to make money and put the newsletter out of business.

There’s a company here in the Portland (OR) area that sends out advertising, coupons, discounts, and offers — from local merchants — on a CD.
Although, I’ve never actually looked at one — I throw them away (my loss) — I would imagine the CD, more than likely, links back to ??? — possibly a central website where folks can browse?
We all know what a CD costs to make. So, the out of pocket costs are extremely small, and the rewards to its producer? Probably real good.
