Right now Stoneyfield Farms yogurt is offering a free, year long subscription to Organic Gardening magazine if you send in 4 of their specially marked foil lids by January 31, 2008. I love this yogurt; I buy it all the time. This is a great deal if you already get this yogurt; but even if you don’t, I’d recommend getting some! The yogurt is amazing, and you’ll get a free year’s worth of organic gardening advice! Can’t get much…
