The first time I came across the Series 2 Lego Minifigs at Walmart, I bought two of them blind at $1.99 a piece. I ended up with the "Explorer" (Yea!) and "Maraca Man" (Eh).
The second time I went to that Walmart, I was armed with a barcode decoder! Alas, the one I was looking for ("The Spartan") was nowhere to be found, so I gave them all a pass.
The third and final time I went to that Walmart, I discovered that the display was gone. They had initially put it in a back corner where the packages could be easily ripped open and stolen, so I have to wonder if this was a factor in the display going bye-bye. I looked around some more, and in a miscellaneous aisle I found exactly one minifig pack hanging from a hook. Such a sad, sad sight, so I took pity on it and laid down $1.99 plus tax on the mysterious loner. What did I get?
