Hi @Christopher_G ,
I don't believe they are registered with EE Perk Discount since when I tried to sign up, I never received the email to verify my account.
I did call customer service yesterday and the agent was able to help me -- they did see that the promo code I was trying to use should be valid, and they weren't sure why code didn't work on the website. They confirmed that the plan I was trying to purchase should be eligible for the discount. As the code is "online only", they could not use it directly to sign me up, but found a way to get me the same discount by phone using a different code.
I believe there is some sort of issue with your promo code validation, as it seems that a handful of codes that should be valid do not work on checkout. I had a similar issue using a discount code from TOTUM. No matter what I put in my basket, the code did not work on checkout.
It is probably worth looking into your end. Luckily, the customer service agent I spoke to was extremely helpful and found a way forward for me.
