I'm guessing that actually means "no purchase by the entrant is necessary to enter or win." So in other words, if you are given some B&H merchandise by someone as a gift or as payment, etc. The rules also say nothing about having to remove the contents from the B&H mailer box that they send these in. Just, "a B&H product being removed from its packaging" which I take to mean the manufacturer's original packaging.
Maybe it's not too late for me to enter after all...lucky I keep everything for all my expnsive purchases...box, plastic wraps, twist ties... Sounds like a re-boxing and un-boxing is in my future!
