Biore Facial Products $3/1 MQ
April's Cosmopolitan magazine comes with a sample of Biore Baking Soda Acne Scrub and a $3 off coupon for any Bioré facial cleanser. This is a relatively high value coupon.
It's the reason why I sometimes get free subscriptions to magazines I wouldn't normally read. These are usually via RewardsGold. Often they have samples and coupons that make them worth the bother. I usually give mine away to schools where they are used for art projects or other educational purposes.
