If there is a Petsmart or Petco, they will sell frozen/thawed. Not all of them will sell live as food. Or possibly if there are any family owned pet store businesses, you could check there. I'm sorry, I have never been to Florida, but hopefully that will help some.
Feel free to ask if you have any more questions.
thanks mate! ive been to both places many times for regular pet food (dogs). but never for a reptile.
