my question was if this was them trying to scare me or if I will actually have something come in mail? If no cops or anything were called
If the cops were never called, this will be at MOST a civil matter.
You can search this and other websites for numerous discussions about "civil demands".
You can also search the internet where you'll find many scholarly articles authored by lawyers in YOUR state, and other states, offering legal opinions about "civil demands".
You possess common sense.
I could demand that YOU pay me $1,000,000 by midnight tonight.
If I did, you'd laugh, or curse at me.
What you wouldn't do is send me so much as $1.00.
I won't bore you by explaining why that would be the proper reaction.
In fact, if we were in high school, and someone demanded that another student hand him five bucks, someone will be administered a thumping.
The laws in many states, yours included, allow merchants to ASK you to pay them money IF they caught you shoplifting some of their trinkets.
If you ignore their requests, the merchant has to take you to court and convince a judge that you must pay them the money.
Even if a merchant did that to you, you could still ignore the judgment.
The merchant would than have to endeavor to collect the judgment.
As a practical matter, these law firms who send these demands aren't going to sue people who ignore the letters, because that would be too costly.
You could also file bankruptcy, and never have to worry about the demand again.
As a practical matter, you could choose to pay the demand, and nothing more should happen.
Which is why the vast majority of people receiving these demands ignore them.
What you do is up to you.
However, as you debate what to do, read this article by THREE Florida licensed attorneys, not some UNKNOWN dude on the internet, then decide:

You can do your own search and discover hundreds of such wise responses.
From this point forward use this as your mantra: I WILL NEVER DO STUPID STUFF, before you consider shoplifting again. Breaking a law will ruin your life, please just obey all of their laws.
