Discount should be fixed. Only one choice for grills now, so don't worry about having to choose one of the other. I think I told some of you that I was going to switch it over to 4 piece only soon, and I just forgot to do it earlier today.
I did a mock purchase using my personal info and every seemed to work right. Just make sure to use the code verbatim as in the email(s) or else it won't work for sure.
Let me know if there continues to be problems and I can just do a direct bill to your email address.
