If you see "An error occurred during your transaction" after entering your payment information, the most common cause of that issue is a problem we are working on related to multiple cities in the same postal code. If your postal code includes multiple cities, try entering one of the other cities as a way to work around the issue as we investigate the root cause.
If your city has alternative spellings (like "Mt. Vernon" vs. "Mount Vernon" or "Lewisville" vs. "West Lewisville"), try both of those. Additionally, if you are in a country with an alphanumeric postal code (like Canada), capitalize the letters in your postal code.
