Got error message “Coupon code usage limit exceeded” when trying to use coupon code from survey. Have never used a coupon code before.
It’s fixed now 
Sorry!
I’ve got the same issue. I didn’t use the coupon before and I’ve done the survey.
The coupon should still be working if you did finish the survey.
Hmmm. I’ve checked again and it seems to be working now. Two days ago it said it was expired.
I’ll place my order tomorrow. I hope it works.
