Free Pound of Cheerios

I went to the Cheerios site and entered the 6 week challenge. They sent me 6 coupons for $1 off Cheerios, then after the 6 weeks they sent me a coupon for a free box of Cheerios. I got the free coupon in the mail so I think I filled out my address in one of the emails they sent me. The coupon does not specify what size of box you can get for free, just that the price has to be below $4.99. The 1 lb box of Cheerios at Safeway was $4.15 so I got that one and the coupon worked for it! I don't know if they are still sending the free Cheerios coupons but it's worth a try.
