It sounds like a real good deal. Make sure you know exactly what you are purchasing, what the total cost will be, and when you will be able to travel. Don't buy over the phone from unfamiliar companies. Never send cash or a check to unfamiliar companies. You must arrange your own transportation to and from Florida.
Some people never get their trips at all.
There are bargains in the travel industry. Sometimes they involve either early purchase or last minute purchases. Sometimes they mean traveling out of the peak season for that destination. There are less expensive destinations. And there are less expensive options, such as a hotel with fewer amenities or a less prime location.
