Yoplait offers a coupon for a free Yoplait Original Yogurt Cup when you fill out this short form. That’s tied with our mention from January as the best freebie offer we’ve seen from Yoplait since last spring. After submitting the form, you’ll receive the coupon by mail within two to four weeks. Limit one offer per household. Deal ends May 31 or after 1,000,000 redemptions.
