Cool Stuff, it definitely pays to buy over time. I preach DCA all the time, and even doing it like you did really helps average out the costs. Especially since you got in during a huge Bull Run, I believe average price was over $30 for 2011. I got in well before that, but your diligence has made our average costs darn near the same. Mine might be a little lower, but I am mentally removing the premiums. I do not have a spread sheet on it, however. Doubt if I could even make a very good guess at it now, and be any more accurate than my running tally in my head LOL!
Keep Stacking! :D
