This incorrect listing of the number of files you are getting is a chronic problem that does not seem to be going away. The only thing you can do to protect yourself is ask realistically,how much one file should cost. I see your $16.00 did include shipping. That's about right for the cost of 1 file. But,I'd certainly buy more than 1 file if they could be shipped in the same box,reducing the shipping cost per file.
