Hello Mary, and thank you for posting to our community!

After checking your account, it looks like you were able to purchase your first class label after all. 

It's possible there may have been a delay between when you added funds to your Endicia First Class account, and when our system was able to recognize those funds. However, refreshing your browser page can often help to sync everything up again.

Please let us know if you have any other questions or concerns.

Happy Shipping!
