I love magic shops. It reminds me of all the joy and wonder of my childhood. So, when I visited Vegas, I thought I'd bring a little of that home to my six year old. The magician at the counter assured me that my son could pull off the simple, yet impressive boxes of flowers in a bag trick. I was sold and they packaged up our sale. My son was so excited, until he opened the box. They gave us one that had been obviously used, and used a lot! The bag was already ripped in two places. The bottom of the boxes are all falling off, and the plastic is all dinged and scratched on the boxes. What a bummer. A twenty dollar bummer. Not cool. I really wanted to like these guys, but I feel like I got hustled. Had the product been new, I would have given them four stars, but since the whole core of our transaction was the product...1 star.
