I went to Walmart tonight and went to the Lego aisle. I saw a box of series 18 CMFs. It had been rummaged through, so I decided not to waste my time. I'm sure the cop was already gone. I looked at the selection of Lego and then went to electronics. I found nothing there that I wanted, so I went back to the Lego aisle for one more check to see if there was anything I couldn't live without.
That's when I saw it! Behind the box of CMFs was another box. How had I not seen it before? This box was sealed. 
I tore the tape off of the box and started feeling the packs on the left side. Success!! I found the cop almost right away. It was a great trip to Walmart tonight. Not often do I say that.
