Hello, user_ndc22v! Thank you for reaching out to us here for help. If you're wondering when your Xfinity promotional discount ends, you're not alone—it’s a common question, and thankfully, it’s easy to find out. You can check your promotion details in two simple ways:

1. On Your Bill Statement
Turn to the third page of your bill.
Look for a message in green text—this section outlines the amount of your promotional discount, how long it lasts, and the exact end date.
If you're viewing your bill online, be sure to open the PDF version for the clearest and most complete view.
2. Through Your Xfinity Online Account
Log in to your account at xfinity.com.
Navigate to your billing section to view current promotions and their expiration dates.

Not only that, but you can also manage your account and make changes by logging into your account online. You can even use the following link to begin!

I hope this information helps, user_ndc22v!
