If you look in the links for document dumps, I believe that the information from the company that manufacturers the tape is in the dump before this last one.
It clearly states that this tape was no longer made after 2007 and none was sold in the state of Florida in 2007. I believe that you will find that it was sold in Florida in 2005/2006 and only about 135,000 rolls were sold, I believe, to Lowes. I also think that this was for the entire state but I could be wrong about that (going from memory here). Even if it was only for the Orlando area, that would still be a small percentage of the total population that would have been able to purchase this tape.
If you check the orignal Duct Tape thread, I believe that there is more information on exactly when and how it was sold.
Someone reported there finding a roll of it (they were from Orlando) in their garage but reported that it was purchased from Home Depot. Only problem with that is that Home Depot did not sell it.
If I have gotten any of the above information incorrect, someone will correct me.
"Greater Orlando has a population of 2,032,496[1] according to the U.S. Census Bureau 2007 population estimates. The size of the city of Orlando is very unusual for a metropolitan area of its size since most of the inhabitants of the area live in the suburbs and surrounding areas in Orange and Seminole counties, whereas the total population of the city proper is only 220,186 people (2006 estimate)."
According to

And I think that the population of Florida as a whole is over 18 million.
