I went and used it at Kroger, and I had 3x $500 on the same purchase. It did not take it off for some reason.

Went to money center to buy my MOs and also asked about it, guy just reached into the register and gave me 6 bucks back after showing him the coupon.

Went to another Kroger and got another on along with 3x $500 and it took that time. Coupon was removed from my card after that.
