I went to the site purchased one, and never recieved an email confirmation, and my account was not charged three days later. I figured I did something wrong and went ahead and ordered another. I got an email within minutes to confirm. Two days later I got the filter. I was thinking, DAMN that has to be the fastest service ever. I was really impressed until the second filter arrived and I double checked my bank website. Needless to say I have two filters. I was going to keep it, but I thought, the hell with it.
