@gollum,

Why do you want to return it? Is it defective?
Quote:I suspect that there is a health related law or regulation prohibit such a resale.
Well, you've been told that by some store clerk. That wouldn't necessarily lead me to "suspect" it. I might in fact "suspect" quite the opposite, i.e., that there is no such law.
