Today on the Clark Howard show I explained to Clark that sometimes companies will mail you free coupons if you send a polite email with your mailing address to their website. I told him I had a list of 50 companies and viewers are looking for the list! We have a page on the site (in the Printable Grocery Coupon section, scroll down) that lists the companies that sent our team coupons as part of a test. Their coupon supply may vary, but it doesn’t hurt to ask and you can get hundreds of dollars of good coupons if you take the time to send some emails. Here’s the list of companies that I referenced on the Clark Howard Show.
