In 50 years, I have never had a puzzle with duplicate pieces: This one had 2!! There was also 3 missing pieces. Having read the reviews, I see now this is very common for this Company to have missing pieces. I contacted them because it would be nearly impossible to add extra pieces to a puzzle without it done on purpose. I called BP because the 2 duplicate pieces and 3 missing pieces was so egregious, I wanted BP to send me a replacement. I sent a detailed letter as to why I was contacting them, not Amazon. I advised that while missing puzzle pieces can happen (though clearly BP has very poor QC given how often it happens in your factory), it is impossible to add extra/duplicate pieces to a puzzle unless it is intended. In my case, there were 2 duplicate pieces! I advised that because of the fact that the additional pieces were intended, or the result of gross negligence, I was looking to BP directly, as the manufacturer, for remedy. Simply, I asked that the puzzle they sold be replaced with one without missing or duplicate pieces. I received a form email that said I should contact Amazon, as that is where I purchased the puzzle. I re-sent the email, and asked them to read it, as I had already explained why I was not contacting Amazon. In response, I received the exact same email.
