ANYONE ABLE TO USE THE $5 OFF COUPON FOR THE MEN'S COMFORT BELT?

Code # 180331. Have been trying for several days to order.

Now with the free ship and 6 flex tried again.

Did not work for me. Just took off the free ship.

Please need to as I have been ordering and need some more incentive to order.

Please reply if anyone knows the reason if any?

Thanks
DISGO
