Mississippi Market is offering a free class on Feb. 18 (registration required) for how to “shop for natural, organic foods without breaking the bank.” You even get coupons! Meanwhile, Seward Co-op is teaching the art of raising chickens to would-be urban farmers on Feb. 19 and Mar. 12. And at the Bloomington Haskell’s? A free class on the wines of Cote du Rhone, “one of the most affordable wine producing regions in the world.” Still time to gut that retirement account.
