Signing up for an e-mail list is probably not at the top of your to-do list. But this one gets you access to exclusive coupons, samples, and discounts for Proctor and Gamble products.
And the thing is, Proctor and Gamble makes a lot of stuff, like products by Olay, Covergirl, NyQuil, Pepto-Bismol and Gillette. Joining is easy.
The e-mail list is run by VocalPoint, which collects feedback from moms through short surveys and focus groups, sometimes for pay. You'll receive a weekly e-mail with info about P&G new products and what other moms are saying. Occasionally you'll get free samples to test out.
If you don't have kids you may not be accepted -- I wasn't. But it's worth a shot if you are a mom and want to get some freebies.
