As far as I know...only K1 has a published code and it is in the "Members Only" section instead of in this public section. I know some don't use a discount code as they want to "confirm" you're a member before giving it to you and too many people when members have access to codes and when they don't renew membership....they still have/use the code. I know I wouldn't publish a code...too many comers and goers over the years. Sounds harsh I guess...but....it's business.
