Update 10/6/10: Samples are gone already (that was fast!). You can still print the $1.00 coupon from their website.
Cream of Wheat is offering to send you a free sample of their new Cinnabon Cream of Wheat flavor. You will need to provide your mailing and email address, and they say to allow 8-12 weeks for delivery. The fine print also says: one sample per household or address, only valid in the US, and supplies are limited (valid until November 3, 2011 or while supplies last).
The website also offers nutritional information on the Cinnabon flavor. You can also print a coupon for $1.00 off an in-store purchase of Cinnabon Cream of Wheat. The coupon page also has another coupon for $1.00 off any Cream of Wheat.
