Hello, Jonanderson123! Welcome to the Xfinity Forums.
Thanks for reaching out to us and I'd be more than happy to assist.
You should be able to apply all your coupons. Are you receiving some error message when trying to activate them?
Jonanderson123, as I have not heard back from you in some time, I have closed this thread to further comments. I hope you were able to apply your final coupons successfully, but if you still need assistance, please feel free to start a new thread.
