Maybe the best $100 I've spent at Costco

Last week Diane and I went to Costco. We weren't there to buy anything in particular and I think that's why I ran into trouble. I started browsing. Not good in most cases. However, I found a cheap underwater camera that turned out to be a decent buy. I am scared to bring my dslr around water. I do it, but it makes me nervous. And after what happened to my iPhone a month ago my water/electronics paranoia is through the roof. So, how could I pass it up? I think it did pretty well...
