Mr. Gold is correct. I routinely advise clients, especially before the conclusion of their criminal theft charge, to avoid/ignore these letters. That or I write a letter explaining that no payment will be forthcoming. Your case is a little different since you were employed there and signed a confession. That said, a Florida law firm is not very likely to file an expensive lawsuit over a $90 theft, especially if they retrieved the alleged stolen merchandise/money. The exorbitant amount is usually "justified" by restocking fees and loss prevention costs.
You might want to consider talking with an attorney about the specifics of your case. Good luck

I would suggest that you ignore the civil demand. It is highly unlikely that they will pursue anything based on the dollar amount at issue. If you are still concerned, consult with local counsel.
