Crystal at Money Saving Mom recently posted about receiving True Lemon samples. I'll second her recommendation--I love the stuff in water, icees, and smoothies. Click here to request your own samples.
And if you fall in love with the stuff like I did, here's an additional deal for you: Coupons.com, Coupon Bug, and Boodle.com have printable coupons for $1 off True Lemon, True Lime, or True Orange products. Boxes of True Lemon packets are regularly priced at $1.99 at Walgreens, so I often pick it up with the coupons (thus making it half price) when I have some extra RRs.
Additionally, if you blog about the True citrus products, you can get 15 free packets in the flavor of your choice. Click here for more details.
