Sorry, no longer available. This coupon has been reset, so go ahead and print two more! Register for a printable coupon to get a free box of Special K cereal (up to $4.49 value) when you buy one box of Special K. If you have an All-K Pass then you can just log in, or fill out the form to register. I just printed two coupons and they expire on February 28. Your free box of Special K has to be either Special K Original or Special K Low Fat Granola Cereal varieties. Thanks to the readers who shared this with me!
