Tell you the same thing we tell everyone else with the same questions:
It is possible for you to be identified and charged depending on what evidence the store has. Will it happen? No one knows. They have until the statute of limitations expires to seek charges. You could receive anything from the proverbial slap on the wrist to the proverbial book being thrown at you. Stay away from the store you were stealing from for a long time, if not forever.
For now, your guilty conscience is your punishment.
