Hi JD2K,
Welcome to the “reality” of the mattress industry … unfortunately 
The lack of meaningful knowledge and factual information (and sometimes integrity) and the willingness to sell a mattress at any “cost” for the sake of a commission or a profit has become more of the “norm” than the exception in the mainstream part of the mattress industry.
In most cases a couple of hours of reading on this site will give you more important and meaningful information about mattresses than the majority of salespeople in mass market outlets who actually sell the mattresses.
As you can see in the information in post #1 here including these mattress shopping guidelines … I wouldn’t suggest buying any mattress unless I was able to make meaningful comparisons with other similar mattresses based on the materials that were inside it. Even a 50% discount on a mattress that is significantly overpriced in the first place doesn’t mean good value … especially if you have to purchase a used floor model and give up a warranty to get it.
Some of the better options and possibilities in the southeast Florida area I’m aware of are listed in post #2 here and in post #2 here (which is mostly duplicate but has a few more detailed descriptions).
Post #245 here and the links inside it may also be of interest regarding your “other” question (which I know you deleted but I did see :))
