I just printed a coupon for a free KFC grilled chicken meal. It includes 2 pieces of grilled chicken, two individual sides and a biscuit for FREE! The coupon is available to print until 11:59pm CMT May 6, 2009. This coupon is good through May 19, 2009, excluding May 10 (Mother's Day).
The site states that you should be able to print the coupon up to 4 times. Be warned that I was only able to print it twice. Go here to print yours now.
