Hum...Let me see...$40 + the $30 for the extra media, I was wrong when I said I paid $25, + 3/4 a can of extra carbon. Add all that up and divide by 2 and $40 is basically half of what I paid. I bought the filter last May, but since I moved I did not open it up until September. It is in excellent condition. I think $40 for what all I am including is very fair. Any other comments from the peanut gallery?...
