How and Where to Advertise
There have been entire volumes written on mail order selling.
For printed information the best way to learn HOW & WHERE to advertise is to go to your newsstand and check through all the magazines carrying large numbers of classified and space ads...magazines like Popular Science, Field & Stream, Outdoor Life, The National Inquirer, etc. Wherever competitive advertising appears on a regular basis, that's where your best advertising will be.
The next step is to write to the magazines (there will be an address in the ad columns) and ask for their Mail Order Classified & Display Rate Cards. These cards give you all the information you need to place an ad. If you need additional help, you can call them and most will provide free counsel on how to place your ad, whether it be classified or display.
