I would contact the courts/store and make sure your address is current. It is your responsibility to make sure that you keep the courts/store informed of your current address.
If the address is incorrect and they send letters in the mail, you cannot use the defense that there was an incorrect address as the courts don't buy it. That could mean warrants issued for your arrest, extra fines and fees attached to the civil demand.
It is not that big of a deal just to call the store and verify that the address you gave them was current and accurate.
Side note, if you have a state issued ID, please make sure that it has your current address as some people move frequently but do not notify the state of their new address resulting letters going to old addresses etc.
