Spices and Flavorings
Test new seasonings in your own kitchen. Visit consumertesting.mccormick.com and sign up. If you're accepted for an at-home study, McCormick will mail you a full-size sample of the test product along with recipes to try. Once you've made one recipe, complete an online survey. Testers may participate four times per year.
Bonus: You get more than a free sample—McCormick also pays volunteers $10 to $15 for home testing, often via amazon.com gift cards.
Sign up at bettycrocker.com, pillsbury.com, livebetteramerica.com or boxtops4education.com; each will send you one sample every month. Across all four websites the samples are the same and might be soup or Nature Valley granola bars. When you create a free Kraft First Taste membership account at kraftfoods.com, choose a featured product to try from the Offers section and you'll be mailed a coupon for a free sample.
Tips: Watch your in-box for e-mail alerts from the first four sites above, and act fast—only the first 10,000 requests are fulfilled. At the Kraft site, fill out surveys about the company's products to boost your chances of getting more coupons in the mail.
