TOURS ON TAPE -- Fall is a wonderful time to take a vacation. The skies may be gray, but the roads are clear, which makes traveling much more fun. Auto Tape Tours, Box 385, Scarsdale, N.Y. 10583, would like to send you their catalog of long-playing tape cassettes that will guide you through most of the country's tourist attractions. Everyone can dawdle along at his own pace. Best of all, you'll find Auto Tape Tours all over the country.

FREE PET BOOKS -- If you don't have a dog, cat, bird or turtle, you probably know someone who does - and who could benefit from a list of free pet booklets and posters covering almost every kind of animal that's likely to be part of the household. Many of these freebies contain information you'd pay several dollars for in the form of a book at the pet store. For the free list, send a long, stamped, self-addressed envelope to Freebies Magazine, Box 5605-P, Santa Monica, Calif. 90405.

WINTER FREEBIES -- Here comes winter, ready or not. With a whole list of freebies we've found, you can be ready and warm.

Start by asking for a free copy of "Winter Survival," a booklet prepared by the Department of Energy that covers everything from winter health hints to driving tips. You'll learn what to do if your heating system fails or if you're trapped in a blizzard. It also contains a complete list of state energy offices.

If that makes you think about saving energy and keeping warm, ask for "How to Save Money by Insulating Your Home," "Energy Savings Through Automatic Thermostat Controls" and "65 Ways to Save Natural Gas."

These money-stretchers all are available free with a postcard request to the Consumer Information Center, Pueblo, Colo. 81009.
